This hearty Mushroom Lasagna recipe is the perfect veggie boost at dinner time! Egg noodles, a rich mushroom ragu and all the cheese! I love my Beef Lasagna recipe, but I have to say, the rich flavor you get from mushrooms takes this to a whole other level!

Why you should make this Mushroom Lasagna!

Ask me if I want beef lasagna or mushroom lasagna and I’ll choose this. Here’s why!

Crispy – you get those yummy crispy edges and crispy cheese top!
Perfectly cooked – I love an al dente pasta and you get that with this recipe by using fresh lasagna sheets!
Delicious flavor – the mushrooms boost so much flavor into the sauce and make it irresistible!
Great make ahead freezer meal! – You can easily freeze this making it a go to easy dinner option and simply reheat in the oven.
Cheaper to make – than a beef lasagna. Have you seen the prices of everything these days? Mushrooms are half the price of meat.

Let’s Talk Mushrooms!

I’m here to tell you this lasagna is just as good as a classic beef lasagna. It has a delicious flavor, and the mushrooms provide a great texture too. Hidden bonus: toddlers can’t tell they’re eating vegetables!

What type of mushrooms to use

You can use any standard variety of mushroom for this recipe. What I mean by that is eating mushrooms, not dried mushrooms, not anything too strong in flavor or chewy in texture. Most mushrooms sold at fruit shops or supermarkets will suit. Mushrooms like:

Button mushrooms
Cup mushrooms
Portobello mushrooms
Swiss brown mushrooms

How to prepare your mushrooms

Make sure you clean your mushrooms. Some mushrooms come cleaned, packaged, and sometimes even sliced. Those usually don’t need washing. But loose mushrooms sold in boxes that you pick yourself can often have traces of manure on them or dirt. You’ll need to wash your mushrooms by hand under some warm running water. For this recipe, there’s no need to dry them.

Ingredients You Need To Make Mushroom Lasagna

Below is a list of some of the key ingredients you need to know about. You can find a full list in the recipe card at the bottom of this post.

All-purpose flour – helps thicken the sauce.
Stock – if you can get it, use mushroom stock, otherwise vegetable stock will work if you’re trying to keep this vegetarian.
Cheese – I used cheddar cheese for the bechamel, but I used a blend of cheddar and mozzarella that I grated myself for the layers and top. I would recommend grating the cheese yourself. It makes a huge difference in flavor, it’s cheaper and it doesn’t have any additives you find in pre-grated cheese.
Mushrooms – the star of the show! I used button mushrooms, they were the cheapest at the fruit shop. Pretty much standard mushroom variety will work. Cup mushrooms, portobello mushrooms or Swiss Brown mushrooms. To clean your mushrooms run them under some water and use your hands to wipe any soil off them.
Tomato paste – use a good quality tomato paste. It adds a little sweetness to the sauce once it’s caramelized a little.
Worcestershire sauce – has a very subtle spiciness to it and adds flavor to the sauce.
Lasagna sheets – My recommendation when making lasagna is to use fresh lasagna sheets and not dried. There are two reasons, 1st, the pasta doesn’t need to be pre-cooked so you save time, 2nd the texture is so much nicer! It cooks more al dente and has some bite compared to pre-cooked which cooks more when baking. In my opinion, that leads to overcooked pasta sheets.

How do I make this vegan?

This recipe is vegetarian and has dairy in it. It uses cheese, milk and butter.

Milk – In place of milk you can use plant-based milk for the bechamel.
Butter – in place of butter with dairy in it, you can use plant-based butter or margarine.
Cheese – this is a trickier one. For the bechamel you can use pretty much any cheese that will melt. For the mozzarella though, it adds a little bit of stretch, if you can find it, use a plant-based cheese that stretches.

How to make Mushroom Lasagna!

Mushroom Sauce

Add the mushrooms to a food processor in 3 batches. Pulse until chopped. Some large pieces are ok. Smaller pieces are ideal if you’re serving this to toddlers.
Mix the flour and some of the stock together in a small bowl until you reach a thin slurry. This mixture will help thicken your sauce.
Add your onions and garlic to a large pot with some oil and cook for 60 seconds on medium high heat.
Next, add the mushrooms all at once and cook until it begins to breakdown a little. Then add the herbs and tomato paste. Stir to coat.
Add the remaining ingredients including the passata and crushed tomatoes and stir. Bring to a gentle simmer. Lower to low heat and cook for 30 minutes with the lid on top. Once cooked, allow to cool at room temperature, or if making the day before, cool at room temp completely, then place in the fridge until ready to use. Up to 2 days in advance.

Bechamel

Add the butter and flour to a large saucepan and stir on medium low heat for about 1 minute. Don’t let it color otherwise your sauce won’t be white.
Next, add the hot milk in about 3 batches stirring each time. It will bubble and steam so be careful.
Once all the milk is in there, add the cheese and nutmeg and stir until melted and well combined. Place the lid on top and allow to cool until ready to use.

Let’s Layer The Lasagna.

Just a note: in the recipe I made a 6-layer lasagna, but the recipe gives you instructions to make a 4 layer lasagna. If you want to make a taller 6-layer lasagna, I’ve left instructions in the notes of the recipe card at the bottom of this page. With that said, let’s layer this lasagna!

Add 1/4 of the sauce at the bottom of the 9×13-inch baking tin and spread evenly.
Add a layer of lasagna sheets.
More sauce.
Then grated cheese. Repeat this another 3 times, finishing with a layer of pasta sheets.

Add the bechamel and spread evenly. Bake for 40 minutes.
Take out of the oven and add some cheese.
Bake until golden.

Why Do The Photos Show 6 Layers But The Recipe Gives Instructions For 4 Layers?

I like a tall lasagna. I like the flatter ones too but I love seeing all those tall layers so I made mine a 7 layer lasagna. The recipe card at the bottom of the post gives ingredients measurements and instructions on how to make a 4 layer lasagna, but if you go to the notes section of the recipe card you can find how to make it a 7 layer lasagna.

I’m Sicilian And Bechamel Is A Dirty Word.

I’m married to a Sicilian so I can sympathize. Sicilian or not though, bechamel is not for everyone so this lasagna can be made without the bechamel on top by simply leaving it out. Finish the lasagna with a layer of sauce and a generous layer of cheese (put the cheese on for the final 15 minutes of baking). The wonderful thing about leaving the bechamel off is that you get ultra-crispy lasagna edges. If you’re not normal and don’t like crispy lasagna edges, loosely cover your lasagna with aluminum foil before baking. Take it off for the final 15 minutes of baking when you add the cheese.

Tips and Tricks For Recipe Success!

Use high quality ingredients for best flavor results!
Don’t skip rest time! It helps the lasagna set a little and cool down. This thing is piping hot when it comes out of the oven. If you slice into it right away, you’ll burn your tongue and it’ll just slide and fall apart.
Make sure mushroom ragu is cooled before using. I would recommend making it the day before and storing in the fridge.
Halving the recipe is easy! Simply halve the ingredient measurements and use a 9×9-inch baking tin.
Pulse your mushrooms in a food processor to make the process quicker. You can also chop these by hand if you don’t have a food processor. If using a food processor, chop them in batches. They won’t all fit or chop properly if they’re added at once. Some larger pieces are ok, but you probably want to make sure the pieces are on the smaller side if you have fussy toddlers. They won’t be able to tell they’re eating vegetables.
