Baked Ravioli Casserole with Sausage and Spinach

Pro tips

• Brown the Italian sausage completely and drain excess fat before layering to prevent a greasy casserole.
• Spread a thin layer of alfredo sauce on the bottom of the baking dish before adding ravioli to prevent sticking.
• Stir the fresh spinach into the alfredo sauce before layering to distribute it evenly and prevent large clumps.
• Cover with foil for the first 20 minutes of baking, then uncover to let the cheese topping brown and crisp.

Substitutions

• Alfredo sauce → marinara sauce mixed with cream (use 1 cup marinara + 0.5 cup heavy cream for similar consistency)
• Italian cheese blend → mozzarella and Provolone (1:1 ratio)
• Sun-dried tomatoes → diced fresh tomatoes or roasted red peppers (same quantity)
• Fresh spinach → frozen spinach, thawed and squeezed dry (use 3 oz to account for moisture loss)

Storage & make-ahead

Store covered in the refrigerator for up to 3 days. Reheat covered at 350°F for 15-20 minutes until warmed through.

Can I use fresh ravioli instead of frozen?

Yes, but add fresh ravioli in the last 15 minutes of baking to prevent mushiness. Frozen ravioli can go directly into the casserole without thawing.

How do I know when the casserole is done?

Bake until the cheese topping is golden brown and the filling is bubbling at the edges, typically 25-30 minutes at 350°F.

Can I make this ahead of time?

Yes. Assemble the casserole, cover with foil, and refrigerate up to 24 hours. Add 5-10 extra minutes to baking time if starting from cold.

What can I use instead of Italian sausage?

Ground beef, ground turkey, or crumbled pancetta work well. Use the same quantity and cook until browned before layering.

Can I reduce the cheese?

Yes, use 1.5 cups Italian blend and 2 tablespoons Parmesan for a lighter dish. The casserole will still be creamy from the alfredo sauce.
