Why you’ll love this recipe

This version of Stuffed Creamy Tomato Basil Pasta Shells brings the best of simple pantry cooking and a few fresh touches. It’s rich but not heavy, thanks to the balance of heavy cream and whole milk ricotta. The tomatoes roast down into a naturally sweet and concentrated sauce while butter and garlic build a cozy base.

1 cup whole milk ricotta cheese
2 cups shredded provolone cheese
3/4 cup basil pesto
1 cup shredded or torn mozzarella

Large skillet or saucepan
2-quart (or similar) baking dish
Wooden spoon and spatula
Tongs and slotted spoon

Prep tips before you start

Preheat your oven to 425°F (220°C). A hotter oven helps the tomatoes roast quickly and deepen in flavor.
Salt the tomato quarters lightly; this draws out moisture and concentrates flavor while they roast.
Prepare an ice bath if you want to stop pasta cooking quickly, but slightly undercooking the shells so they’re al dente is best since they’ll finish in the oven.

Step-by-step directions

The following directions are rewritten for clarity while following the same sequence as the original. Read through once before starting, and have all ingredients at hand.

Place the quartered tomatoes, quartered yellow onion, smashed garlic cloves, and fresh thyme leaves on a large baking sheet. Scatter a pinch of salt, a grind of black pepper, and a little chili flakes over the vegetables. Dot everything with the 6 tablespoons of salted butter.
Roast the vegetables in the preheated oven at 425°F (220°C) until the tomatoes are softened and lightly caramelized and the onions begin to brown, about 25–30 minutes. Stir once halfway through roasting to promote even caramelization.
When the vegetables are roasted, transfer them to a blender or food processor. Add 1/2 cup heavy cream. Blend until smooth and creamy. Taste and adjust seasoning with additional salt, black pepper, or chili flakes as desired. Set this creamy tomato sauce aside.
Bring a large pot of salted water to a boil. Add the 1 pound of jumbo shells and cook until just shy of al dente according to package directions (they will finish cooking in the oven). Drain the shells and rinse briefly with cool water to stop cooking and make them easier to stuff.
In a large bowl, combine 1 cup whole milk ricotta cheese, 2 cups shredded provolone cheese, and 3/4 cup basil pesto. Mix until homogenous and adjust seasoning with a pinch of salt and pepper. This is your filling for the shells.
Working carefully, spoon the ricotta-provolone-pesto mixture into each jumbo shell. Arrange the filled shells seam-side up in a buttered 2-quart baking dish or an equivalent-size casserole.
Spoon the blended creamy tomato sauce evenly over and around the arranged shells. Use enough sauce to coat the bottoms and sides so the shells will bake in sauce rather than dry out. If any filling is left over, dollop it between shells or reserve for another use.
Sprinkle 1 cup shredded or torn mozzarella over the top of the sauced shells. This will melt into a golden, bubbling layer.
Bake the dish in the oven at 375°F (190°C) until the sauce is bubbling around the edges and the cheese is melted and lightly browned, about 20–25 minutes. If you prefer a deeper brown on top, broil for 1–2 minutes while watching closely.
Remove the baking dish from the oven and let it rest for 5 minutes so the sauce settles. Garnish with fresh basil leaves. Serve hot, spooning sauce and little pools of melted cheese around each shell.

Serving suggestions

These Stuffed Creamy Tomato Basil Pasta Shells pair beautifully with a simple green salad dressed in lemon and olive oil, crusty bread to mop up every last bit of sauce, or roasted seasonal vegetables. For extra brightness, finish each plate with an extra drizzle of basil pesto or a squeeze of fresh lemon.

Make-ahead and storage

You can assemble the shells and keep them covered in the refrigerator for up to 24 hours before baking. When ready, bake straight from the fridge, adding a few extra minutes to the bake time so the dish heats through. Leftovers keep in an airtight container in the refrigerator for 3–4 days; reheat covered in a 350°F (175°C) oven until warmed through, or microwave individual portions.

Variations and swaps

Cheese: If you want even creamier filling, add an extra 1/4 cup ricotta or swap half the provolone for fontina. The amounts listed work beautifully as written.
Greens: Stir 2 cups chopped baby spinach or cooked, squeezed-dry chopped kale into the ricotta-provolone mixture for a green boost.
Heat: Increase or decrease chili flakes to taste. A pinch brings warmth; a generous sprinkle adds real bite.
Vegan option: Replace dairy ingredients with plant-based ricotta, vegan shredded cheeses, and vegan butter — keeping all amounts the same will maintain balance.

Troubleshooting

If your sauce seems too thin after blending, return it to a saucepan and simmer over medium-low heat until it thickens slightly, then add to the shells.
If shells are difficult to stuff, they may be overcooked. Next time, cook them a minute or two less than package directions so they hold their shape.
For the creamiest filling, ensure the ricotta is well-drained: place it in a fine-mesh sieve lined with cheesecloth for 15 minutes and press gently to remove excess liquid.

Flavor notes

The roasted tomatoes in this recipe bring natural sweetness and a concentrated tomato character that contrasts beautifully with the herbaceous pesto. Butter and garlic create a silky mouthfeel in the sauce, while provolone gives a gentle tang and smooth melt. The ricotta filling keeps each bite pillowy and light, preventing the dish from feeling too dense.

Final thoughts

The recipe scales well, reheats beautifully, and rewards a little advance prep. Whether you’re feeding a crowd or making weekday leftovers that feel like a treat, this dish is a reliable, delicious choice.

Method

Preheat the oven to 425°F (220°C).
In a large baking dish, toss the quartered tomatoes, quartered onion, smashed garlic, thyme leaves, butter, and a generous pinch of salt, black pepper, and chili flakes.
Bake the vegetables for 20–30 minutes, until the tomatoes start to char and release their juices.
Carefully transfer the roasted vegetables to a blender or food processor and puree until smooth; return the puree to the baking dish and stir in the heavy cream until combined.
While the sauce bakes, bring a large pot of salted water to a boil and cook the jumbo shells until al dente according to package directions; drain and cool slightly so they can be filled.
In a medium bowl, mix the ricotta, shredded provolone, and 1/2 cup of the pesto until evenly combined.
Spoon about 1 tablespoon of the cheese mixture into each cooked shell, then arrange the filled shells in the baking dish with the tomato-cream sauce.
Drizzle the remaining 1/4 cup pesto over the shells, sprinkle the mozzarella evenly on top, and bake for about 15 minutes, until the cheese is melted and bubbly.
Remove from the oven, garnish with fresh basil, and serve warm.
