Every time I make kousa mahshi, the stuffed squash that my mom made for us growing up and that my daughters ask for to this day, I core the squash by hand. Piece by piece, the soft, pale filling comes out and gets set aside. For most people, that filling goes straight into the trash. In my mother’s kitchen, it never did.
My mom has been making this kousa cores recipe for as long as I can remember. The moment the squash is cored, that flesh goes into a pan with olive oil, garlic, dried mint, sumac, and pomegranate molasses. Within about 15 minutes, it transforms into one of the most quietly delicious dishes in our whole Lebanese repertoire. It is tangy from the sumac and pomegranate molasses, garlicky and aromatic, with that mint running through it. We eat it straight from the pan with a spoon. My daughters eat it the same way.
I only make this recipe when I am already coring squash for kousa mahshi. I have never once grabbed squash from the store specifically to make this. But when it happens, it is one of those happy kitchen moments where something about to be discarded becomes the most talked-about thing on the table.
This is Lebanese zero-waste cooking at its best, and it is the kind of recipe that gets passed down not because it is famous, but because it is genuinely, deeply good. A few of my other favorite comfort foods include classic thick hearty chili, hearty Instant Pot durum wheat soup with beef shanks, and vegetarian bulgar and tomato pilaf (burghul w banadoura).

What Are Kousa Cores?
When you make kousa mahshi (Lebanese stuffed squash), the first step is to hollow out each squash with a corer. This removes the soft inner filling, leaving a hollow shell to be filled with the rice and meat mixture. The removed inner flesh is what Lebanese cooks call the kousa cores.
The cores are the pale, tender, slightly seedy center of the squash. The texture is softer and more delicate than the squash’s firm outer wall. Unlike the shell, which holds its shape during the long simmer, the core cooks down quickly and almost melts into the pan when sautéed. It absorbs flavor beautifully, which is why a short sauté with garlic and a handful of bold seasonings produces something that tastes deeply developed despite being ready in minutes.
In Lebanese home cooking, throwing away kousa cores is considered wasteful. Generations of cooks have turned them into a quick-cooked side dish, a fried-egg breakfast (the cores fried with eggs and seasoned with salt and pepper is another beloved tradition), or a simple sauté like this one.
It is one of those recipes that does not appear in cookbooks or on restaurant menus precisely because it is so embedded in everyday home life that nobody thought to write it down. My mother has made this version with garlic, dried mint, sumac, and pomegranate molasses.
Ingredients
Kousa squash cores: The soft inner flesh from cored squash, chopped small for even cooking. This recipe works with green zucchini, yellow squash, or Tatuma squash (Mexican squash). Mild and slightly watery, it releases moisture, creating a light broth and pairs well with bold flavors.
Garlic: This is one of the two most essential ingredients in the recipe, alongside pomegranate molasses. Use fresh garlic, not powder, and sauté in olive oil to build the aromatic base of the entire dish.
Dried mint: It adds a fresh fragrance that lifts the earthy squash flavor and balances the tangy flavors. Do not skip it. The mint is not optional here.
Sumac: A tangy, slightly fruity spice that adds acidity, similar to lemon but more complex.
Pomegranate molasses: It is the ingredient that makes the recipe. Just 1½ teaspoons are enough to give the entire dish its distinctive sweet-sour backbone. Do not skip it and do not substitute with regular molasses.
Olive oil: Adds richness to the dish. Use good-quality extra virgin.
Salt: Season to taste at the end.
Zucchini vs Squash: What Is the Difference?
If you have ever wondered whether it matters which type of squash you use when making kousa mahshi, the short answer is: not much. And the same goes for these kousa cores.
Botanically speaking,zucchini is a type of summer squash. Both belong to the Cucurbita pepo species and are part of the broader squash family. Zucchini is the most common variety of summer squash and is typically dark green or striped. Yellow squash has a pale golden skin and a very slightly sweeter, milder flavor. The two are so close in texture and moisture content that they can be swapped one for one in almost any recipe without any noticeable difference in the final result.
In Lebanese cooking,the word kousa refers to the small, pale green Lebanese zucchini traditionally used for kousa mahshi. In practice, Lebanese home cooks use the terms kousa, zucchini, and squash interchangeably. Green zucchini, yellow squash, and Tatuma squash (also called Mexican squash, the closest in shape and flavor to the traditional Lebanese kousa) are all treated as the same category of ingredient and swapped freely depending on what is available at the market.
The cores that come out of any of these varieties are equally delicious in this recipe. The soft inner flesh behaves the same way in the pan regardless of which squash it came from: it cooks down quickly, releases its natural moisture, and absorbs the garlic, mint, sumac, and pomegranate molasses beautifully.
Quick Reference
- Green zucchini: mild, slightly grassy flavor, most widely available in American grocery stores
- Yellow squash: slightly sweeter and milder, produces cores with the same soft texture and flavor-absorbing quality
- Tatuma squash (Mexican squash or calabacita): closest to traditional Lebanese kousa in flavor and texture, found at Latin grocery stores and farmers’ markets
- Mixed cores: if you cored both green and yellow squash for your kousa mahshi, use the cores from both together for a slightly more layered flavor in this dish.
Substitutions and Variations
Use Eggplant Cores: If you are making stuffed eggplant (batinjan mahshi or sheikh el mahshi) instead of stuffed squash, you can prepare the scooped-out eggplant filling the same way. Eggplant cores have a more pronounced, slightly earthier flavor than kousa filling. Salt the eggplant cores and let them sit for 10 minutes, then rinse and pat dry before cooking to draw out excess bitterness and moisture. The garlic, mint, sumac, and pomegranate molasses combination works beautifully with eggplant as well. Consider adding a splash of lemon juice to brighten the dish or a spoonful of tomato paste for richness.
Use Lemon Juice: If you cannot find pomegranate molasses, a squeeze of fresh lemon juice adds tartness in its place. The flavor will be brighter and more straightforwardly citrusy rather than the complex sweet-sour depth of pomegranate molasses, but the dish will still be very good.
Use Fresh Mint: For a more vibrant, slightly brighter flavor, use fresh mint instead of dried mint. Ensure to add fresh mint at the very end of cooking rather than sautéing it with the squash, so the flavor stays fresh, and the color stays green.
Add Texture: Finely diced onion or bell pepper adds a pleasant texture contrast to the soft, melt-in-your-mouth squash filling.
Add Heat: A pinch of red pepper flakes for a spicy kick. You can also add a spoonful of spicy red pepper paste stirred in toward the end of cooking, which gives the dish a welcome kick without overpowering the other flavors.
Add Richness: A spoonful of tomato paste stirred in with the squash adds a subtle depth and a slight sweetness, especially if pomegranate molasses is not available.
How to Make Lebanese Kousa Cores
Step 1: Prepare the Squash Filling
After coring the squash for kousa mahshi or any other stuffed squash recipe, collect all the removed inner filling into a bowl.
Chop it into small, roughly uniform pieces, about half an inch in size, for even cooking.
Step 2: Sauté the Garlic
Heat the olive oil in a medium pan over medium-high heat.
Add the minced garlic and sauté for about 30 seconds, stirring constantly, until it becomes fragrant and just barely golden.
Step 3: Cook the Squash Filling
Add the chopped squash cores to the pan and stir to coat them with the garlic-infused oil.
Add the dried mint, sumac, and pomegranate molasses. Stir well to combine everything evenly. Taste and add salt as needed.
Step 4: Simmer Until Tender
Reduce the heat to low. Let the mixture cook and simmer gently for about 15 minutes, stirring occasionally.
As the squash cooks, it will release its natural moisture, creating a light, fragrant broth in the pan. The filling will soften considerably, and the flavors will deepen and meld together.
Step 5: Serve
Serve warm, either with the natural broth that has formed in the pan or drain the broth if you prefer a drier result. I eat it with a spoon straight from the pan. It is also excellent at room temperature.
Recipe Tips
Uniform chopping. The flesh should be chopped into small, roughly uniform pieces before cooking so it cooks down evenly. Uniform cutting ensures everything cooks at the same rate.
Do not skip the simmer. The biggest mistake people make with this recipe is not cooking the cores down long enough. You need to let the squash filling sauté and then simmer properly so the moisture releases, the flavors meld, and the texture becomes soft and almost silky. Rushing this step leaves the dish tasting raw and underdeveloped.
Use generous garlic. Garlic is one of the two most important ingredients in this recipe, and using extra is actively encouraged. The garlic infused into the olive oil at the start is the flavor backbone of the whole dish.
Never skip the pomegranate molasses. If there is one ingredient that makes this recipe taste the way it is supposed to taste, it is the pomegranate molasses. Do not substitute it, do not reduce it, and do not leave it out. It gives the dish its distinctive sweet-sour depth that you cannot replicate any other way.
The mint matters too. Both the pomegranate molasses and the dried mint are non-negotiable. Together, they create the flavor that makes this dish instantly recognizable to anyone who grew up eating Lebanese home cooking.
Try it cold too. I prefer it warm, but it is also genuinely delicious at room temperature or cold from the fridge, almost like a Lebanese-spiced zucchini relish. Scoop it onto bread or alongside rice, either way.
What to Serve with Kousa Cores
This dish is best served the same day you make Lebanese kousa mahshi, as a simple side to the main stuffed squash pot.
Serve it straight from the pan with warm pita bread for scooping, the most natural and most beloved way. You can also spoon it over plain rice as a light, flavorful topping.
Serve it as part of a mezze spread alongside hummus, fattoush, and grape leaves.
Topped with a fried egg for a simple, very Lebanese breakfast or light lunch, the classic family use for squash cores.
It also works beautifully as a light lunch the next day, eaten cold or briefly reheated, with bread on the side.
Storage Tips
Refrigerator: Store leftover kousa cores in an airtight container in the fridge for up to 3 days. The flavor actually deepens overnight as the garlic and pomegranate molasses continue to infuse the squash filling. Leftovers taste just as delicious, especially with a small refresher of dried mint and salt when reheating.
Reheating: Reheat gently over low heat on the stovetop. Add a small splash of water if needed to loosen the dish and prevent it from drying out. Stir in a pinch of fresh dried mint and a tiny pinch of salt before serving to revive the flavor. The microwave also works for a quick single-serving reheat.
Freezing: It is not recommended for this recipe. The high moisture content of the squash flesh causes it to become waterlogged and mushy when thawed. This dish is best made fresh and enjoyed within 3 days.
Frequently Asked Questions
Kousa cores are the soft inner flesh of the squash that is removed when coring kousa for stuffed squash dishes like kousa mahshi.
Yes. Green zucchini, yellow squash, Tatuma squash (Mexican squash), or any other variety used for stuffed squash all work here. The flavor and texture of the cores will vary slightly between varieties, but the recipe works with all of them. Eggplant cores from stuffed eggplant dishes can also be used with minor adjustments (see the Substitutions section).
Pomegranate molasses is a thick, dark syrup made by reducing pomegranate juice until it becomes intensely flavored and slightly sweet with a pronounced tartness. You can find it at Middle Eastern grocery stores, at specialty or international food stores, and online.
You can substitute lemon juice for a similar tartness, but the depth and complexity of pomegranate molasses cannot be fully replicated. If you enjoy this recipe, pomegranate molasses is worth having in your pantry, as it appears in many Lebanese dishes and lasts a long time. A small bottle goes a long way.
Yes. Make it a day ahead and store it covered in the fridge. The flavor deepens overnight. Reheat gently on the stovetop with a splash of water and a pinch of fresh dried mint before serving.
