Ingredients
Main Ingredients
- 12 oz jumbo pasta shells, uncooked
- 1 tbsp olive oil
- 3 cup marinara sauce
- 2 cup whole milk ricotta cheese
- 2 cup shredded mozzarella cheese for the filling
- 0.5 cup shredded mozzarella cheese for topping
- 0.75 cup finely grated Parmesan cheese
- 12 oz frozen chopped spinach, thawed and squeezed dry
- 1.5 tsp minced garlic
- 1 tsp Italian seasoning
- 0.25 tsp crushed red pepper flakes optional heat
- 1 tsp kosher salt plus more for pasta water
- 0.5 tsp ground black pepper
- 2 tbsp fresh basil, chopped divided
Instructions
Preparation Steps
- Heat oven to 375°F. Lightly oil a 9×13-inch baking dish.
- Boil shells in salted water until very al dente, 1–2 minutes shy of package time. Drain and rinse to cool.
- Warm olive oil in a small skillet over medium heat. Cook garlic until fragrant, about 30 seconds, then cool slightly.
- Stir together ricotta, 2 cups mozzarella, Parmesan, squeezed-dry spinach, Italian seasoning, red pepper, salt, pepper, and half the basil. Fold in the cooled garlic.
- Spread about 1½ cups marinara over the bottom of the baking dish.
- Fill each shell with a heaping spoonful of the cheese mixture. Nestle stuffed shells into the sauced dish.
- Spoon remaining marinara over shells and sprinkle the ½ cup mozzarella on top. Cover the dish tightly with foil.
- Bake 20 minutes covered. Uncover and bake 10–15 minutes more until bubbly and lightly browned. Broil 1–2 minutes if you like extra color.
- Rest 5 minutes. Scatter remaining basil over the top and serve warm.
Notes
Variation: Add a pinch of nutmeg to the filling, or stir a splash of cream into the marinara for a richer bake. To make ahead, assemble up to 24 hours in advance, cover, and refrigerate; add 5–10 minutes to the bake time from cold. Leftovers reheat well, or freeze the baked shells for up to 2 months.
