How to Make Summer Stuffed Shells
- Prep & Boil Shells: Preheat your oven to 350°F. Boil the jumbo pasta shells in salted water according to package instructions until they are al dente. Drain and let them cool enough to handle.
- Sauté Vegetables: In a large oven-safe skillet or Dutch oven (preferably cast iron), heat the olive oil. Add the diced onion and minced garlic, season with kosher salt and black pepper, and cook until softened and fragrant. Stir in the chopped zucchini and corn, cooking for 5-6 minutes until everything is tender. Remove from heat and let it cool slightly.
- Make Filling: In a spacious bowl, mix together the ricotta cheese, lightly beaten egg, 1 cup of mozzarella, ½ cup of parmesan, and ⅓ cup of pesto. Don’t forget to season with salt and pepper. Gently fold in the cooled vegetable mixture until fully incorporated.
- Assemble: Spread the marinara sauce evenly in the skillet where you sautéed the veggies. Carefully stuff each jumbo shell with 2-3 tablespoons of the creamy filling, placing them directly into the marinara in a single layer. If necessary, use an additional baking dish for any overflow.
- Top & Bake: For that extra layer of flavor, dollop the remaining pesto on top of the shells (optional but recommended). Sprinkle the remaining mozzarella over everything. Bake uncovered for 25-30 minutes, or until the top is bubbly, hot, and golden brown.
- Serve: Remove from the oven and let it rest for a few minutes. Garnish with extra parmesan and fresh basil before serving warm.
Optional: Drizzle with a bit of olive oil before serving for added richness.

Make Ahead Options
These Summer Stuffed Shells are ideal for meal prep, allowing you to savor delicious homemade comfort food with minimal effort during busy nights! You can fully assemble the dish and refrigerate it up to 24 hours before baking. Just cover the pan with foil to maintain moisture and prevent any drying out. When you're ready to cook, simply remove the foil and bake it for an additional 10-15 minutes, as chilled shells may take a bit longer to heat through. You can also prepare the filling and sauté the vegetables up to 3 days in advance; store them in airtight containers in the refrigerator. This way, you can enjoy a hearty meal without the rush, and they’ll be just as scrumptious!

Summer Stuffed Shells Recipe FAQs
How do I choose the best zucchini for my Summer Stuffed Shells?
When selecting zucchini, look for firm, smooth-skinned specimens without dark spots or blemishes. The ideal size is around 6-8 inches long as they tend to be more flavorful and tender; large zucchinis can be watery.
How should I store leftover Summer Stuffed Shells?
Leftover Summer Stuffed Shells can be stored in an airtight container in the fridge for up to 3-4 days. To reheat, cover with foil and warm in the oven for about 20 minutes at 350°F or use the microwave for a quicker option.
Can I freeze my Summer Stuffed Shells?
Absolutely! You can freeze assembled but uncooked shells for up to 2-3 months. Make sure to wrap the dish tightly in plastic wrap, then cover with aluminum foil. Thaw them overnight in the fridge and bake for an additional 5-10 minutes.
What should I do if my filling seems watery?
If your filling is too watery, it might be due to the zucchini's moisture. To fix this, you can shred the zucchini, sprinkle it with salt, and let it sit for about 15 minutes. Then squeeze the excess moisture out before adding it to your ricotta mixture. This will ensure a creamy and not overly wet filling.
Are there any dietary considerations for Summer Stuffed Shells?
For a gluten-free option, use gluten-free pasta shells. If you have allergies, be mindful of the cheeses; consider using dairy-free alternatives. Additionally, incorporate more vegetables for a fiber boost or use a vegetarian protein if desired, like crumbled tofu mixed with seasoning for a heartier filling.
How can I enhance the flavors of my Summer Stuffed Shells?
To elevate the flavors, consider adding fresh herbs like thyme or oregano into the filling. Also, a dollop of pesto on top before baking not only boosts the herbaceous flavor, but it also adds an eye-catching pop of color, enhancing your presentation.
