This Ricotta Stuffed Zucchini Involtini turns humble summer squash into something that feels special enough for company yet easy enough for a weeknight. Tender ribbons of zucchini wrap around a creamy ricotta filling, all nestled in tomato sauce and blanketed with melty mozzarella. It is my go to when I want the comfort of lasagna without the heaviness of all those noodles.
I first threw this together one August evening when my garden gave me more zucchini than I knew what to do with. My husband declared it better than the eggplant version we usually make, and now it lands on our table almost every week during squash season.
Ingredients
- Zucchinis: choose thick and uniform ones so the slices are wide enough to stuff and roll without tearing
- Olive oil: helps the zucchini soften and lightly char in the oven so use a good quality extra virgin variety
- Salt and pepper: draws out moisture and seasons the squash before it ever meets the filling
- Ricotta cheese: the heart of the filling so look for a whole milk version for the creamiest texture
- Grated parmesan: adds a salty savory depth that balances the mild ricotta
- Fresh basil leaves: brings brightness and that unmistakable Italian aroma so pick leaves that are deep green and unblemished
- Garlic clove: one minced clove infuses the filling with warmth without overpowering it
- Egg: binds the filling so it holds together neatly inside each roll
- Tomato sauce: use your favourite jarred sauce or a homemade one you love since it carries so much of the flavor
- Shredded mozzarella: melts into that irresistible golden top layer
- Fresh basil to garnish: a final flourish that makes the whole dish feel fresh
Step-by-Step Instructions
- Prep the Zucchini:
- Slice each zucchini lengthwise into planks about one quarter inch thick. Toss the slices with olive oil, salt and pepper, then lay them on a baking sheet and bake at 400 degrees F for 10 minutes. This softens them just enough to roll while coaxing out extra moisture so your final dish stays firm rather than watery.
- Make the Filling:
- In a mixing bowl combine the ricotta, parmesan, chopped basil, minced garlic, salt, pepper and egg. Stir until everything is fully blended and smooth. Taste a tiny bit and adjust the seasoning here since the filling should be well seasoned on its own.
- Make the Rolls:
- Spoon a small amount of filling onto one end of each zucchini slice, then roll it up snugly. Spread a thin layer of tomato sauce across the bottom of an oven safe pan or baking dish. Nestle each roll seam side down into the sauce, spoon a touch more sauce over the top, then scatter the shredded mozzarella across everything.
- Bake:
- Return the dish to the oven at 400 degrees F and bake for 8 to 10 minutes until the rolls are warmed through and the cheese is bubbling and golden. Finish with a handful of fresh basil right before serving.
The ricotta filling is my favorite part of this whole recipe. My grandmother always said the secret to good ricotta was a little more parmesan than you think you need, and she was right every single time. Whenever I mix that filling the smell of garlic and basil takes me straight back to her tiny kitchen.
Storage Tips
Keep any leftovers in an airtight container in the fridge for up to three days. Reheat gently in a 350 degree F oven until warmed through so the cheese re melts without the zucchini turning mushy. You can also freeze the assembled unbaked dish tightly wrapped for up to two months, then thaw overnight before baking.
Ingredient Substitutions
If you are out of ricotta a well drained cottage cheese works in a pinch though the texture will be slightly looser. Swap the mozzarella for provolone or fontina if you want a sharper melt. Eggplant slices can stand in for zucchini when you want a heartier version, just salt and drain them first to remove bitterness.
Serving Suggestions
I love serving these rolls with a crisp green salad dressed simply in lemon and olive oil. A hunk of crusty bread is perfect for mopping up the extra tomato sauce even though this is meant to be low carb. For a bigger spread pair it with a light soup or a plate of marinated olives to start.
Cultural Context
Involtini simply means little bundles in Italian and the technique of rolling thin slices around a filling shows up all over Italy with meat, eggplant and vegetables. This zucchini version is a lighter riff on the classic and reflects how Italian home cooks make the most of whatever the garden offers in high summer.
Recipe FAQs
- → How thick should I slice the zucchini?
- Aim for about 1/4 inch thick slices. Slicing too thin makes the zucchini hard to roll, as it will shrink further while baking.
- → What is the best tool for slicing zucchini?
- A mandolin gives the most even slices, but you can also use a vegetable peeler or a sharp knife.
- → Can I make this dish ahead of time?
- Yes, you can assemble the rolls in the baking dish ahead of time and bake them when ready to serve for best results.
- → Why did my dish turn out watery?
- Adding too much sauce in the pan can make the dish watery. Use a modest amount so the zucchini stays firm.
- → Is this recipe vegetarian and low-carb?
- Yes, it is a vegetarian dish and naturally low in carbs since zucchini replaces pasta while still delivering plenty of protein.
