How to make baked spinach ricotta pasta shells
You’ll cook the shells, mix the filling, stuff, and bake until everything is hot and melty.
- Cook the shells in well-salted water just until al dente. Drain and rinse briefly with cool water so they don’t stick.
- Prep spinach: if using frozen, thaw and squeeze out as much water as possible (this matters for a thick, creamy filling).
- Mix the filling with ricotta, spinach, half the mozzarella, Parmesan, egg, garlic, seasoning, salt, and pepper.
- Sauce the dish: spread a layer of marinara in the bottom of a baking dish to prevent sticking.
- Stuff the shells and arrange them in the dish. Spoon more marinara over the top.
- Top with cheese and bake until bubbly and lightly golden.
Tips for the best stuffed shells
- Don’t overcook the pasta. Slightly firm shells are easier to stuff and finish cooking in the oven.
- Squeeze spinach dry. Excess moisture can make the filling runny and watery the sauce.
- Use a piping bag (or zip-top bag). Snip a corner and pipe the filling into shells fast with less mess.
- Cover first, then uncover. Foil helps everything heat through; uncovering at the end helps the cheese brown.
Make-ahead, storage, and freezing
- Make ahead: Assemble up to 24 hours in advance, cover, and refrigerate. Bake as directed, adding a few extra minutes if cold.
- Refrigerate leftovers: Store covered up to 4 days. Reheat in the oven or microwave until hot.
- Freeze: Freeze assembled (unbaked) shells tightly wrapped up to 3 months. Thaw overnight in the fridge before baking, or bake from frozen covered until hot, then uncover to brown.
What to serve with spinach ricotta stuffed shells
- Garlic bread or warm focaccia
- Simple green salad with Italian vinaigrette
- Roasted broccoli, zucchini, or asparagus
