Spinach Lasagna Recipe don’t get much cozier than this Mushroom and Spinach Lasagna — a melty, bubbly, totally satisfying bake that turns simple greens and fungi into a weeknight superstar. If you want a dish that comforts like grandma’s cooking but reads like restaurant-level yum? This is your vibe.

Recipes With Spinach And Mushrooms: intro to the recipe

This lasagna layers tender pasta sheets with a savory mushroom-spinach sauté, creamy ricotta, tangy marinara, and a crown of molten mozzarella and Parmesan. It works for a Vegetarian Sunday Dinner or a no-fuss family meal any night. It’s hearty, fridge-friendly, and — best part — even the meat-eaters at your table will nod in approval.

What makes this lasagna so irresistible?

  • Umami overload. Sautéed cremini or button mushrooms give deep savory notes that mimic the richness you miss when skipping meat.
  • Creamy balance. Ricotta + mozzarella create a lush, pillowy texture that hugs each layer.
  • Greens for days. Fresh spinach wilts into the mix for color, nutrients, and a lighter mouthfeel.
  • Sauce that ties it together. Marinara keeps it bright and stops the dish from feeling too heavy.

Got picky eaters? This is one of those Spinach Mushroom Recipes that sneaks vitamins into every forkful without shouting “green!” at the table. Win-win.

Ingredients (with short notes)

  • 9 lasagna noodles — cook al dente so they finish perfect after baking.
  • 2 tbsp olive oil — good for sautéing; extra-virgin is fine.
  • 1 small onion, finely chopped — sweetness base.
  • 3 cloves garlic, minced — aroma + punch.
  • 1 lb mushrooms (cremini or button), sliced — the savory backbone.
  • ½ tsp dried thyme — subtle herby warmth.
  • Salt & pepper — season smartly.
  • 3 cups marinara sauce — use a quality jar or homemade.
  • 2 cups ricotta cheese — creamy binder.
  • 1 cup shredded mozzarella — melty goodness.
  • ½ cup grated Parmesan — sharp finish.
  • 2 cups fresh spinach, chopped — fresh green goodness.
  • Fresh basil, to garnish — fragrance and color.

This list makes a classic Spinach Lasagna Recipe simple, flexible, and reliable.

Quick how-to (simple steps)

  1. Preheat oven to 375°F (190°C). Grease a 9×13-inch dish.
  2. Cook noodles until al dente. Drain and set aside separated so they don’t stick.
  3. Sauté aromatics & mushrooms: Heat oil, cook onion until soft (3–4 min), add garlic 1 min, then mushrooms + thyme + salt/pepper. Cook until moisture evaporates and mushrooms brown.
  4. Add spinach: Toss in chopped spinach and stir until wilted (~2–3 min). Remove from heat.
  5. Assemble: Spoon a thin layer of marinara on the pan, lay 3 noodles, spread half the ricotta, half the mushroom-spinach mix, sprinkle ⅓ mozzarella & Parmesan. Repeat; finish with sauce + remaining cheese.
  6. Bake covered 25 minutes, uncover and bake 10–15 more until bubbly and golden. Let cool a bit, slice, serve.

Pro tip: For an ultra-creamy texture, fold a beaten egg into the ricotta. It helps the filling set beautifully.

The story behind the recipe

I wanted a lasagna that felt indulgent without the meat circus. Mushrooms deliver texture and depth, spinach brings freshness, and the cheeses tie it all into a cozy package. This is one of those Mushrooms And Spinach combos that started as a weekday experiment and graduated to holiday rotation. Friends called it “fancy green lasagna” — I take that as a compliment.

Pro tips for best results (read this — seriously)

  • Use room-temperature ricotta and cream cheese (if adding) to mix smoothly.
  • Brown your mushrooms well. Don’t steam them — you want caramelized edges for maximum flavor. High heat + patience = major payoff.
  • Salt as you go. Mushrooms and cheese both bring saltiness; adjust gradually.
  • Don’t overcook the noodles. Al dente is your friend; they’ll soften in the oven.
  • Let the lasagna rest 10–15 minutes before slicing. This helps the layers set and keeps slices intact.
  • FYI: If your marinara is acidic, add a pinch of sugar to mellow it out.
  • IMO: Fresh herbs matter. Toss chopped basil between layers or sprinkle on top for brightness.

Bold tip: Brown the mushrooms well and remove excess moisture — that keeps the lasagna from becoming watery.

Variations to try (because variety rules)

  • Add roasted veggies: Zucchini, eggplant, or roasted red peppers play nicely.
  • Make it vegan: Swap ricotta and mozzarella for plant-based alternatives; use nutritional yeast for umami.
  • Go luxe: Stir truffle oil (sparingly) into the mushroom mix for an upscale twist.
  • Protein add-on: Stir in cooked lentils or crumbled tempeh for extra heft without meat.
  • Creamy béchamel: Replace ricotta with a light béchamel for a silkier texture — French-Italian fusion!

These tweaks make this a flexible Recipe With Spinach you can adapt week after week.

Best way to serve

Serve warm with a crisp side salad and a bright vinaigrette to cut through the richness. Add a loaf of crusty bread to mop up sauce — nobody will complain. For Vegetarian Sunday Dinner, pair with a chilled white (think Pinot Grigio) or a light red (Gamay).

Presentation hack: Wipe a hot knife between cuts for clean slices. Garnish with torn basil and a drizzle of extra-virgin olive oil.

Storage & leftovers (quick tips)

  • Refrigerate: Store tightly covered for 3–4 days.
  • Freeze: Portion into airtight containers or freeze whole (wrapped well) up to 3 months. Thaw overnight in the fridge before reheating.
  • Reheat: Oven works best — 350°F covered for ~20 minutes. Microwave works in a pinch but may get soggy.
  • Leftover idea: Chop and toss into a skillet with an egg for breakfast lasagna — trust me.

FAQs (fast, useful answers)

Can I use frozen spinach?

Yes. Thaw and squeeze out excess moisture first so the layers don’t get watery.

Do I need to pre-cook noodles?

I recommend cooking to al dente. Some no-boil noodles work well too, but they often require more sauce.

Can I make this ahead?

Absolutely. Assemble the night before, refrigerate, then bake when ready. You’ll likely add 10–15 minutes to baking time.

How do I keep the top from burning?

Cover with foil for most of the bake. Remove during the last 10–15 minutes to brown.

Can I add meat?

Yes—brown ground beef or Italian sausage, drain, and fold into the mushroom mix for a meatier version.

What mushrooms work best?

Cremini or baby bella have great flavor; shiitake adds a meaty chew. Mix varieties for complexity.

Is this spicy?

Not by default. Add red pepper flakes to the mushroom sauté if you want heat.

How do I make it gluten-free?

Use gluten-free lasagna sheets (or swap with thinly sliced eggplant for a low-carb option).

Can I double the recipe?

Sure—use a larger pan or two 9×13 dishes.

Any tips for ultra-cheesy layers?

Mix grated mozzarella into the ricotta and add extra mozzarella between layers.

Description

A cozy, meat-free take on the classic—layers of tender pasta, a savory mushroom-and-spinach filling, creamy ricotta, melty mozzarella, and bright marinara. Simple to build, seriously satisfying to eat.


Ingredients

Scale
  • 9 lasagna noodles
  • 2 tbsp olive oil
  • 1 onion, finely diced
  • 3 garlic cloves, minced
  • 1 lb mushrooms (cremini or button), sliced
  • ½ tsp dried thyme
  • Salt and black pepper, to taste
  • 3 cups marinara sauce
  • 2 cups ricotta cheese
  • 1 cup shredded mozzarella cheese
  • ½ cup grated Parmesan cheese
  • 2 cups fresh spinach leaves, chopped
  • Fresh basil leaves, for garnish


Instructions

Prep & oven

  1. Preheat the oven to 375°F (190°C). Lightly oil a 9×13-inch baking dish.

Cook the noodles

  1. Boil a large pot of salted water. Cook the lasagna noodles until al dente according to package directions. Drain and separate so they don’t stick.

Make the mushroom-spinach filling

  1. Warm the olive oil in a large skillet over medium heat. Sauté the diced onion until soft (about 3–4 minutes). Add the garlic and cook 1 minute more.

  2. Add the sliced mushrooms, thyme, and a pinch of salt and pepper. Cook until the mushrooms release their liquid and that liquid evaporates and the edges begin to brown.

  3. Stir in the chopped spinach and cook until it wilts (about 2–3 minutes). Remove from heat and set aside.

Assemble the lasagna

  1. Spoon a thin layer of marinara over the bottom of the prepared baking dish. Lay down 3 lasagna noodles. Spread half of the ricotta over the noodles, then half of the mushroom-spinach mixture. Sprinkle with about one-third of the mozzarella and Parmesan.

  2. Repeat: another layer of sauce, 3 noodles, the remaining ricotta, the rest of the mushroom mixture, and another third of the cheeses. Finish with the last 3 noodles, the remaining marinara, and the remaining mozzarella and Parmesan on top.

Bake

  1. Cover the dish with foil and bake for 25 minutes. Remove the foil and bake 10–15 minutes more, or until the top is bubbling and lightly golden.

Rest & serve

 

  1. Let the lasagna sit for a few minutes so the layers settle. Garnish with torn fresh basil and cut into squares. Serve warm.

    • Meaty option: Stir in cooked ground beef or Italian sausage to the mushroom mixture for a hybrid version.
  • Storage & reheating
    • Refrigerate: Keep leftovers in an airtight container for 3–4 days.
    • Reheat: Warm single portions in the microwave or reheat the whole tray in a 350°F (175°C) oven about 20 minutes (cover with foil to prevent overbrowning).
    • Freeze: Assemble and wrap tightly (plastic + foil) and freeze for up to 3 months. Bake from frozen, adding extra time, or thaw overnight then bake as usual.
