Toss 2 cups diced zucchini, 1½ cups sliced cremini mushrooms, 1 cup diced red bell pepper, and 3 cloves minced garlic with 2 tbsp olive oil, salt, and pepper. Spread on a baking sheet and roast at 400°F for 18-20 minutes until golden and tender. Stir in 1 cup packed baby spinach while still hot.

Add 12 dry lasagna noodles to the boiling salted water and cook according to package directions until just al dente, about 8-10 minutes. Drain and lay them flat on a lightly oiled baking sheet in a single layer to prevent sticking while you prepare the remaining components.

Melt 4 tbsp unsalted butter in a medium saucepan over medium heat. Whisk in ¼ cup all-purpose flour and cook for 1-2 minutes.

Season with salt and pepper.

Reduce oven to 375°F. Spread ½ cup béchamel on the bottom of the prepared dish.

Repeat layers twice more, finishing with the final 3 noodles topped with remaining béchamel and 1 cup shredded mozzarella cheese.
