Stuffed zucchini in tomato sauce

I experienced this on a Wednesday when I decided to make something "healthy" with zucchini, but still with meat, because that's how we do it—no meal goes without meat. The first time I scooped out the zucchini so aggressively that I made holes all the way through the skin, and the filling spilled everywhere. But they were eaten anyway, slightly battered, and everyone laughed, saying they were a "summer model," more airy. Since then, I've been trying to scoop them out with a smaller spoon and some patience, without forcing it. Anyway, this recipe has become something I make almost weekly—sometimes for dinner, sometimes for lunch, and each time I change something up because I don't have the patience to make it the same way.

People ask me how long it takes and how difficult it is—let me be straightforward: it takes about an hour and a bit for the whole process, including washing the dishes. I usually make enough for four people, which means about two halves of zucchini per person, and there’s never anything left. It's not exactly for total beginners, but it's not rocket science either—you just need a bit of patience when scooping and don’t rush the oven.

I make this recipe often because zucchini is available year-round where I live, and it helps when I'm in a hurry or don't feel like chopping up fancy food. Plus, you pop them in the oven, and you don’t have to stand by the stove. The kids eat them (well, they avoid greens if they can spot them, but I trick them with the parmesan), and they taste even better cold the next day. Additionally, if you have leftover ground meat or some stray parmesan, you can toss it in there, and no one will notice.

1. I wash the zucchinis. I cut them lengthwise (I try to make the cuts as straight as possible; if they’re curved, it annoys me when filling them, but I manage). With a small teaspoon, like a coffee spoon, I scoop out the insides, but I don’t throw it away! I set it aside. The idea is to leave about half a centimeter of flesh, so they aren't too thin. If I hit large seeds, I scoop those out too; no one wants those in the filling. I chop the flesh as finely as I can, and if it’s too watery, I squeeze it a bit.

2. In a large bowl, I throw in the ground meat (usually a mix of beef and pork, but I add chicken if that’s what I have), the chopped zucchini flesh, two eggs (no more, or it will be too soft), grated parmesan (this adds flavor and binds the mixture well), salt, pepper, and breadcrumbs (depending on how wet the meat is—if it’s too soft, I add more breadcrumbs). I always add parsley, whether frozen or fresh, and no one notices the difference. I mix everything with my hands, not with a spoon; it’s easier to feel if it’s too soft or too firm. If it’s too soft and runny, that’s okay, just don’t let it pool.

3. In a smaller bowl, I mix diced tomatoes (usually from a can, as they’re more convenient), olive oil (about four tablespoons, eyeballing it), sugar (to cut the acidity; I don’t know why, but without sugar, it sometimes turns out too sour), oregano, and dried basil (or whatever I have in the cupboard; thyme works too). Salt and pepper to taste. If I see it’s too thick, I add half a glass of water so it doesn’t burn on the edges when I put the tray in the oven.

4. I pour this sauce directly into the tray, so the zucchinis sit on it, not directly on the metal.

5. I fill the zucchini halves with the meat mixture. I don’t pack them too tightly, but I don’t leave them empty either, so they don’t dry out too much in the oven. I place them with the filling side up, a bit snug if necessary (it’s fine if they stick together), right in the tomato sauce.

6. I put the tray in the oven at 180 degrees Celsius, preheated. They should be ready in about 30 minutes, but I check on them: when they’re nicely browned on top and you can easily pierce the zucchini with a fork, they’re done. If they seem dry, I can pour a bit of the sauce from the tray over them, so they don’t get too crusty.

7. I take them out and let them rest for about 10 minutes; otherwise, everything is too liquid. That is, if anyone can resist diving in right away.

Important tip: don’t put too much salt in the mixture, especially if the parmesan is salty or if the canned tomatoes already have salt. I once made that mistake, and they turned out almost inedible; I had to put sour cream on top to mask the flavor.

You can replace the meat with chopped mushrooms for a vegetarian version—I’ve made it during Lent like that, adding some grated telemea cheese. Cheese also works. If you feel like it, you can add a bit of chopped garlic to the filling or even in the sauce, but not too much, as it can overpower the rest. For a more flavorful sauce, a splash of white wine can be added, but it’s not mandatory. For a complete meal, you can serve them with simple pilaf or rice, or even with a cabbage salad (fresh or pickled, depending on the season). Sometimes, I’ve also included some new potatoes in the oven to make sure everyone gets enough. For a drink, a semi-dry white wine works, something not too aromatic, or, if it’s summer, a light beer.

There are countless variations—you can make stuffed zucchini just with vegetables (a mix of eggplant, bell peppers, onion), or if you have the patience, you can use quinoa or rice instead of meat. You can substitute breadcrumbs with ground oats if you want something more diet-friendly. I’ve also tried it with turkey meat—it’s a bit bland, but if you add double the parmesan and some finely chopped red bell pepper, it turns out quite good. A bit of hot pepper in the sauce works too, if you like things spicy.

They pair best with a simple salad, like a green salad with lemon, or if you want something heartier, with soft polenta. For the kids, I’ve also served a bit of mashed potatoes on the side to avoid comments about “more greens.” Some prefer to sprinkle grated cheese on top of the zucchinis just before putting them in the oven, but I find they become too heavy, like lasagna.

Frequently asked questions (I’ve received these too):

- How do you prevent the zucchinis from getting too soft?
If you scoop too deeply, you’re left with only the skin, and they become mushy in the oven. Leave a bit of flesh and don’t bake them too long; 30-35 minutes is sufficient. It’s better to check them at 25 minutes than to pull out “soup” from the oven.

- Can it be made without meat?
Yes, and it turns out great. Use chopped vegetables (mushrooms, carrots, bell peppers, onion), possibly an egg for binding, and parmesan or cheese. Or use cooked lentils, but make sure to drain the water well.

- What can I use instead of parmesan?
Any hard cheese works, even cheese or salty telemea (well-drained), or sheep cheese. I’ve used Grana Padano when I couldn’t find parmesan, and no one noticed.

- How do you make the tomato sauce not sour?
Sugar—a teaspoon is enough. You can also add grated carrot to the sauce (quickly sautéed in oil first) if you don’t want any sugar at all.

- Can the stuffed zucchinis be frozen?
It’s tricky because they tend to become watery upon thawing. But if you really want to, freeze them raw and stuffed, and bake them directly from frozen (extend the cooking time by 10-15 minutes).

- Can I make them during Lent?
Yes, replace the eggs with two tablespoons of breadcrumbs and add more greens and mushrooms or hydrated soy granules.

Nutritional values: It’s quite a balanced dish if you don’t overdo it with breadcrumbs or parmesan. For one serving (two large zucchini halves with sauce), you’re looking at about 350-400 kcal, with around 20 g of protein, 14-16 g of fat (depending on the meat used), and about 20-22 g of carbohydrates (if you’re not eating it with bread or another side). Many shy away from ground meat, but if you choose lean meat or even chicken, it’s a good option. Zucchini provides water, fiber, and some vitamins, while the tomato sauce adds vitamin C. The cheese (parmesan or whatever you choose) also provides calcium. It’s not a diet meal, but it’s not a calorie bomb either, especially if you don’t serve it with bread.

How to store and reheat: If there are leftovers (unlikely), I put them in the fridge in a covered tray. They last for 2-3 days without any issues. To reheat, the easiest way is in the oven for 10-12 minutes at 170 degrees, covered with foil, so they don’t dry out. You can also use the microwave, but not for more than 2-3 minutes; otherwise, the meat toughens. If you see that the sauce has thickened too much, add a tablespoon of water or tomato juice on top.

Ingredients (and why I use them):
- 4 large zucchinis – the base, they hold the filling, becoming sweet and soft in the oven
- 250 g ground meat mix (beef/pork or chicken) – protein, flavor, binds the filling
- 5-6 sprigs of fresh parsley (or frozen) – for flavor and a bit of freshness
- 2 eggs – bind the filling so it doesn’t spill in the oven
- 5 tablespoons grated parmesan – deepens the flavor, helps with texture and binding
- 4 tablespoons breadcrumbs – absorb excess moisture, keep the filling firmer
- 1 teaspoon dried seasoning (like “Secret of Flavor” vegetable mix) – adds extra flavor, but it’s not mandatory
- salt, pepper – essential, regulate the taste
For the sauce:
- 400 g diced tomatoes in their own juice – base, provide moisture and acidity
- 1 teaspoon sugar – balances the acidity of the tomatoes
- 1 teaspoon dried oregano – classic flavor, works with tomato sauces
- 1 teaspoon dried basil – adds a touch of freshness
- 4 tablespoons olive oil – aids in baking and adds flavor
- salt, pepper – to taste, regulates the sauce

 Ingredients: 4 large zucchinis, 250 g mixed ground meat, 5-6 sprigs of fresh parsley, 2 eggs, 5 tablespoons grated Parmesan cheese, 4 tablespoons breadcrumbs, 1 teaspoon vegetable seasoning, salt, pepper. Tomato sauce: 400 g diced tomatoes in sauce, 1 teaspoon sugar, 1 teaspoon dried oregano, 1 teaspoon dried basil, 4 tablespoons olive oil, salt, pepper.
