This creamy spinach and ricotta stuffed shell bake is comfort food at its best — rich, satisfying, and easy to make ahead.

👨🍳 Step-by-Step Cooking Guide
1. Boil Pasta Shells
- Use a large pot of salted water.
- Cook shells until just al dente — they’ll finish in the oven.
- Drain and set on a tray to prevent sticking.
Tip: Stir gently while cooking to avoid breakage.
2. Mix the Ricotta Filling
- Combine ricotta, chopped spinach, shredded mozzarella, Parmesan, egg, minced garlic, Italian seasoning, salt, and pepper.
Tip: Squeeze spinach dry in a clean towel for best texture.
3. Make the Cheese Sauce
- Melt butter in a saucepan, whisk in flour, cook 1–2 minutes to eliminate raw flavor.
- Gradually add milk while whisking.
- Simmer until thick.
- Add shredded cheese, garlic powder, a pinch of nutmeg (if using), and salt.
Troubleshooting: If sauce is too thick, whisk in a splash of milk.
4. Stuff the Shells
- Fill each shell with 1–2 tablespoons of filling.
- Place them seam-side up in a greased baking dish.
5. Assemble and Bake
- Pour cheese sauce evenly over shells.
- Top with extra shredded cheese.
- Bake at 375°F (190°C) for 25–30 minutes until bubbly and golden.
Optional: Broil for 2–3 minutes at the end for a golden top.
