½ teaspoon dried oregano
-
Pinch of ground nutmeg

Instructions
-
Cook lasagna noodles according to package instructions. Drain and set aside on a parchment-lined surface to prevent sticking.
-
Make the sauce:
-
In a large skillet, melt butter over medium heat.
-
Add garlic, onion, and mushrooms; sauté until soft and browned (about 7–9 minutes).
-
Sprinkle in flour and stir constantly for 1–2 minutes to form a roux.
-
Gradually whisk in milk until smooth and thickened (5–7 minutes).
-
Stir in basil, oregano, nutmeg, salt, and pepper. Remove from heat.
-
-
Prepare ricotta filling:
-
In a bowl, mix ricotta, spinach, 1 cup mozzarella, ½ cup Parmesan, and parsley.
-
-
Assemble lasagna:
-
Preheat oven to 375°F (190°C).
-
Spread a small amount of sauce on the bottom of a 9×13-inch baking dish.
-
Layer 3 noodles, half the ricotta mixture, one-third of remaining sauce, and 1 cup mozzarella.
-
Repeat with 3 more noodles, remaining ricotta, one-third sauce, and 1 cup mozzarella.
-
Top with final 3 noodles, remaining sauce, remaining ½ cup Parmesan, and extra mozzarella if desired.
-
-
Bake uncovered for 35–40 minutes, or until golden and bubbly. Let rest for 10 minutes before slicing.
Notes
Fresh spinach can be used (sautéed and drained) in place of frozen.
Add red pepper flakes for a bit of heat.
Can be assembled ahead and refrigerated before baking.
