What You’ll Need (and Easy Substitutions)

This lasagna is full of flavor, but you can easily tweak it based on what you have:

• Mushrooms – Cremini mushrooms add depth, but button, shiitake, or portobello work too.
• Spinach – Fresh is best, but frozen is fine—just make sure to drain it well.
• Ricotta Cheese – Gives the filling a creamy texture. Cottage cheese works as a lighter alternative.
• Lasagna Noodles – Regular, oven-ready, or gluten-free noodles all work. If using no-boil noodles, make sure there's plenty of sauce to keep them soft.
• Béchamel Sauce – This smooth white sauce ties everything together. If you're short on time, a mix of heavy cream and Parmesan makes a quick substitute.
• Cheese – Mozzarella melts beautifully, and Parmesan adds sharpness. You can also try fontina, provolone, or Gruyère for extra depth.

How to Make the Best Creamy Spinach & Mushroom Lasagna

Lasagna might seem complicated, but if you take it step by step, it’s easy to put together.

1. Cook the Vegetables

• Heat some olive oil in a large pan over medium heat.
• Sauté the onions until soft, then add garlic and cook for a few seconds.
• Add the mushrooms and cook until they’re golden and tender.
• Stir in the spinach and cook just until wilted. Season with salt, pepper, and oregano, then set aside.

2. Make the Ricotta Mixture

• In a bowl, combine ricotta cheese, an egg, grated Parmesan, a pinch of salt, black pepper, and a little nutmeg.
• Mix until smooth and set aside.

3. Prepare the Béchamel Sauce

• Melt butter in a saucepan over medium heat.
• Whisk in flour and cook for about a minute, stirring constantly.
• Slowly pour in milk while whisking to prevent lumps.
• Cook until the sauce thickens slightly, then stir in salt, pepper, and mozzarella until melted.

4. Assemble the Lasagna

• Preheat the oven to 375°F (190°C).
• Spread a thin layer of béchamel sauce on the bottom of a baking dish.
• Add a layer of lasagna noodles.
• Spread half of the ricotta mixture over the noodles, followed by half of the mushroom and spinach mixture.
• Pour a layer of béchamel sauce over the vegetables.
• Repeat the layers, finishing with a final layer of noodles, the remaining béchamel, and a generous sprinkle of cheese.

5. Bake

• Cover with foil and bake for 30 minutes.
• Remove the foil and bake for another 15 minutes until golden and bubbly on top.
• Let it rest for about 10 minutes before slicing to help the layers hold together.

Tips for the Best Lasagna

• Slightly Undercook the Noodles – If you’re boiling them first, leave them slightly firm so they don’t get mushy while baking.
• Drain Excess Liquid from the Veggies – Mushrooms and spinach release a lot of water, so make sure to drain them well to avoid a watery lasagna.
• Use Freshly Grated Cheese – It melts better than pre-shredded cheese, which contains anti-caking agents.
• Let It Rest Before Slicing – This helps it firm up and makes cutting much easier.

Make It Your Own

• Gluten-Free Option – Use gluten-free noodles and swap the flour in the béchamel for a gluten-free alternative.
• Add Protein – Toss in some shredded chicken, tofu, or cooked sausage for extra heartiness.
• Try Different Cheeses – Experiment with goat cheese, feta, or smoked gouda for a unique twist.
• Add a Little Spice – A pinch of red pepper flakes or cayenne can give it a bit of heat.

How to Store and Reheat

• Refrigerate – Store leftovers in an airtight container for up to four days.
• Freeze – Slice into portions, wrap tightly, and freeze for up to two months.
• Reheat:
  • Oven – Cover with foil and bake at 350°F (175°C) for about 20 minutes.
  • Microwave – Heat individual slices for 2-3 minutes until warmed through.
  • From Frozen – Let thaw overnight in the fridge before reheating.

What to Serve With It

This lasagna is filling on its own, but it pairs well with:

• A Simple Green Salad – A fresh, crisp salad balances out the richness.
• Crusty Bread or Garlic Bread – Great for soaking up the extra sauce.
• Roasted Vegetables – Carrots, zucchini, or asparagus add color and nutrition.
• A Glass of Wine – A light white wine like Chardonnay or a mild red like Pinot Noir complements the creamy flavors.
