Spicy Pesto and Cheese Stuffed Zucchini Involtini has become my favorite way to use up the overload of summer zucchini. Imagine thin ribbons of zucchini tucked around a rich mixture of pesto and cheese, then baked in a tangy, herby tomato sauce until bubbling and golden. This dish brings out everything I love about summer flavors with a kick of spice and creamy comfort all in one bite.
When I first made this for a backyard dinner, everyone fought for seconds—the pan was scraped clean and there were happy requests for the recipe all around.

Step-by-Step Instructions
- Prep the Oven and Baking Dish:
- Preheat your oven to a hot 425 degrees F and lightly grease your baking dish so nothing sticks later
- Make the Sauce Base:
- Heat olive oil in your largest pot over high heat until shimmering then crumble in chicken sausage and brown it for up to 8 minutes Every bit should lose all pinkness Lower heat before tossing in bell pepper crushed tomatoes oregano thyme red pepper flakes and a pinch each of salt and pepper Let the sauce simmer for a good 10 minutes so excess liquid reduces Taste along the way adjust salt pepper or spice
- Slice the Zucchini Ribbons:
- With a mandolin or sharp vegetable peeler carefully slice long ribbons from top to bottom about quarter inch thick Lay them side by side on paper towels This helps them dry out slightly making them easier to roll Sprinkle lightly with salt and let sit while you prep filling
- Mix the Cheesy Filling:
- In a bowl combine ricotta fontina and most of the pesto For even blending stir briskly with a fork Taste a bit to check for seasoning The filling should be creamy and spreadable
- Assemble the Involtini:
- Spread most of the tomato sauce in your prepared baking dish For each roll lay two zucchini ribbons side by side Scoop a generous spoonful of cheese filling onto the center Gently roll into a loose coil and place seam side down into the sauce Keep going with the rest lining them up snugly Add the rest of your sauce on top Drizzle remaining pesto so it weaves over the zucchini Tuck in torn mozzarella between the rolls
- Bake Until Bubbly:
- Slide the dish into the oven and bake until the cheese melts and turns golden on top and everything smells amazing This usually takes about 30 minutes Let cool a few minutes before piling on fresh basil

Storage Tips
Zucchini involtini keeps well refrigerated for up to three days Let the dish come to room temperature before reheating for even warmth For freezing assemble everything but skip baking Cover well and freeze for up to a month Add ten minutes to baking time straight from freezer You might want to add extra sauce as zucchini will release more liquid when reheated
Ingredient Substitutions
Swap the chicken sausage for turkey or even a plant based sausage for a vegetarian-friendly version Ricotta can be subbed with cottage cheese in a pinch but drain it first Smoked provolone stands in well for fontina If you do not have bell pepper diced eggplant works nicely
Serving Suggestions
Serve hot as a main dish with a loaf of crusty Italian bread or garlic knots A fresh green salad with lemon vinaigrette brightens the meal This pairs beautifully with chilled white wine or sparkling water Add grilled corn or marinated olives for a backyard feast

Cultural Context

Recipe FAQs
- → How do you get zucchini ribbons thin enough to roll?
Use a mandolin or vegetable peeler to slice zucchini lengthwise into 1/4-inch wide strips. Lay ribbons on paper towels to drain excess moisture and sprinkle lightly with salt for pliability.
- → What cheeses work best for the filling?
A blend of whole milk ricotta and shredded fontina provides creaminess and melt. Mozzarella adds a gooey topping, and you can substitute other melting cheeses if preferred.
- → Can I make this dish vegetarian?
Yes, simply omit the chicken sausage from the sauce and consider boosting flavor with additional herbs or chopped mushrooms for a savory note.
- → Does store-bought pesto work?
Both homemade and quality store-bought pesto work well. Use your favorite variety, but opt for one with plenty of fresh basil for the brightest flavor.
- → How do you prevent the dish from becoming watery?
Salting the zucchini and letting it rest draws out excess moisture. Gently blot or squeeze ribbons dry with paper towels before rolling and baking.
- → Can this be made ahead of time?
Assemble the dish up to the baking step, cover, and refrigerate. Bake just before serving for best texture and flavor.
