Ingredients
- 12 no-boil lasagna noodles: to form the layers of our dish.
- 2 tbsp olive oil: for sautéing our vegetables.
- 1 large yellow onion, diced: adds a sweet, savory base.
- 4 cloves garlic, minced: for that essential aromatic flavor.
- 16 oz cremini mushrooms, sliced: provide a deep, earthy flavor.
- 5 oz fresh spinach: adds a pop of color and nutrients.
- 1/4 cup all-purpose flour: helps thicken our creamy sauce.
- 4 cups whole milk: creates a rich and luxurious base for the sauce.
- 1 cup vegetable broth: adds another layer of savory flavor.
- 1 tsp dried thyme: pairs perfectly with the mushrooms.
- 1/2 tsp ground nutmeg: a warm, classic touch for creamy sauces.
- 2 cups shredded whole milk mozzarella cheese: for that perfect stretchy melt.
- 1 cup grated Parmesan cheese: adds a salty, nutty flavor.
- 1 (15 oz) container whole milk ricotta cheese: for creamy, dreamy layers.
- 1 large egg: helps bind the ricotta layer.
- Salt and black pepper to taste: for seasoning every component.
Instructions
- Preheat your oven to 375°F. Lightly grease a 9×13 inch baking dish.
- In a large skillet, heat the olive oil over medium heat. Add the onion and cook until softened, about 5 minutes. Add the garlic and cook for one more minute until fragrant.
- Add the sliced mushrooms to the skillet. Cook, stirring occasionally, until they have released their liquid and turned a beautiful golden brown, about 8-10 minutes. Add the spinach in handfuls, stirring until it wilts. Season with salt and pepper, then remove the vegetable mixture from the skillet and set it aside.
- In the same skillet, melt the butter over medium heat. Whisk in the flour and cook for one minute to form a roux. Gradually whisk in the milk and vegetable broth until the mixture is smooth. Bring to a gentle simmer, whisking constantly, until the sauce thickens enough to coat the back of a spoon, about 5-7 minutes. Stir in the thyme and nutmeg. Remove from heat.
- In a medium bowl, combine the ricotta cheese, egg, 1/2 cup of the Parmesan cheese, and a pinch of salt and pepper. Mix until smooth.
- Now, let’s assemble! Spread about 1/2 cup of the white sauce into the bottom of your prepared baking dish. Arrange 4 lasagna noodles over the sauce. Top with half of the ricotta mixture, spreading it gently. Spoon half of the mushroom and spinach mixture over the ricotta, then drizzle with about 1 cup of the white sauce. Sprinkle with 1/2 cup of mozzarella.
- Repeat the layers once: noodles, remaining ricotta, remaining veggies, 1 cup of sauce, and 1/2 cup mozzarella.
- Top with the final 4 noodles. Pour the remaining white sauce over the top, ensuring the noodles are completely covered. Sprinkle with the remaining mozzarella and Parmesan cheeses.
- Cover the dish tightly with foil and bake for 25 minutes. Uncover and bake for another 15-20 minutes, until the cheese is golden and bubbly around the edges. Let the lasagna stand for 15 minutes before slicing and serving. This rest time is crucial for neat slices!
Variations & Substitutions
This recipe is wonderfully flexible. For a richer sauce, you can substitute half the milk with heavy cream. Not a fan of cremini mushrooms? Button mushrooms work just fine. If you need a dairy-free version, use your favorite plant-based milk, broth, and cheeses. For a protein boost, stir in some shredded cooked chicken or smoked turkey into the vegetable layer. You can even use regular lasagna noodles; just boil them according to package directions first.
Serving Ideas & Pairings
This lasagna is a star on its own, but it plays well with others for your holiday dinner ideas. I love serving it with a bright, simple arugula salad with a lemon vinaigrette to cut through the richness. Some warm, crusty garlic bread is never a wrong answer either. It’s a fabulous main dish for your Christmas meal ideas that pairs beautifully with lighter sides. And for a real treat, a glass of sparkling cider or a non-alcoholic sparkling grape juice makes it feel extra festive.
Oven Temperatures
The ideal temperature for baking this lasagna is 375°F. This allows it to cook through evenly without the top browning too quickly while covered. If you find your oven runs hot or cold, an oven thermometer is a baker’s best friend. If the top isn’t as golden as you’d like after uncovering, you can broil it for just a minute or two at the end—but watch it closely!
Storage & Reheating
Leftovers? They might be even better the next day! Cool the lasagna completely, then cover tightly and store in the refrigerator for up to 4 days. To freeze, wrap individual portions tightly in plastic wrap and foil, or store the whole pan well-wrapped for up to 3 months. Thaw in the refrigerator overnight before reheating. The best way to reheat is in a 350°F oven, covered with foil, until warmed through (about 20-30 minutes for a large portion). You can also microwave single servings for a quick lunch.
