• Preheat oven to 375 °F.
• Grease a 9x13 extra deep casserole dish (~3 inches).

Meat

• In a pan over medium-high heat, heat olive oil.
• Add you meat and seasonings. Mix well.
• Cook until done, approximately 8-10 minutes.

Spinach-Ricotta Filling

• In a pan over medium-high heat, melt butter.

• Add onion and garlic. Mix.
• Add remaining ingredients and mix until smooth and completely incorporated.

Sauce

• In a pan over medium-high heat, melt butter.
• Add garlic and cook until fragrant.
• Add remaining ingredients and cook until sauce thickens.

Assembly

• If you do not have oven ready lasagna noodles (it would say on the box), cook and drain them now.
• In the bottom of your greased pan, spoon 1/2 of the sauce on the bottom and sprinkle 1/3 of the meat on top.
• Add a layer of noodles. I cut mine in order to fully cover the dish.
• Spread 1/2 the spinach ricotta filling and 1/3 of the meat over the lasagna noodles.
• Add another layer of noodles.
• Spread remaining spinach ricotta filling and meat over the lasagna noodles.
• Add remaining noodles or enough to cover the filling.
• Spread remaining sauce on top.
• Sprinkle mozzarella and parmesan on top.
• It is all cooked, so bake to desired cheese crispiness. I baked mine for 30 minutes.
