Spinach Mushroom Pasta Bake | Vegan (2024)

This vegan pasta bake with spinach and mushrooms is wonderfully creamy, fabulously delicious and easy to make – It’s a simple plant-based pasta gratin casserole recipe without eggs, dairy milk, butter, heavy cream or cheese!

Easy Healthy Vegan Pasta Bake Recipe

If you’ve been following me for a while, you know that I love the combination of pasta, mushrooms and spinach! So why not make a quick, easy, no-fuss pasta bake with whole grain rigatoni, cremini mushrooms and spinach in a creamy, light cream sauce, topped with tofu feta and vegan cheese?

This pasta gratin recipe is not only delicious, but healthy too! While the whole grain pasta keeps you full for a long time, the mushrooms and spinach provide plenty of vitamins, nutrients and plant-based protein. Since sautéed mushrooms naturally have a meaty texture, you won’t miss any meat in this dish either.

However, if you don’t like mushrooms, feel free to replace them with other vegetables or omit them completely and use more spinach instead. And if you love carbonara pasta, feel free to mix in finely diced smoked tofu that will remind of the taste of ham. There are so many options when making this casserole recipe – get creative!

Ingredients needed for this recipe

To make this vegan spinach and mushroom pasta bake, you’ll only need a few simple ingredients that are easily available everywhere. These are:

• Pasta: I used whole grain rigatoni, but you can of course use your favorite kind of pasta or gluten-free pasta.
• Vegan butter: or margarine. Alternatively, olive oil or canola oil will do too.
• Onions and garlic: for the aromatic base.
• Mushrooms: Use cremini or any other mushrooms you like.
• Spinach: fresh or frozen.
• Flour: I use all-purpose flour, but you can also use gluten-free flour.
• White wine: this is optional, but it adds more flavor to the sauce and provides a better taste.
• Vegetable broth: or unsweetened plant milk and more spices.
• Vegan crème fraîche: you can buy vegan sour cream in the supermarket or make your own cashew cream cheese. More alternatives are mentioned further down in the post.
• Spices: fresh parsley, dried Italian herbs, salt, pepper and nutmeg.
• Toppings: for topping, I use tofu feta and vegan grated cheese. Also, vegan parmesan for garnish.

How to make Vegan Spinach and Mushroom Pasta Bake

As always, I recommend checking out the recipe video and these step-by-step instructions first. Then you’ll find the full recipe with exact measurements in the recipe card below!

Step 1: Sauté onions, garlic, mushrooms.

First, sauté the onions in vegan butter until translucent. Next, add the garlic and sauté for a few minutes. Then sprinkle with some flour, add the wine, vegetable broth and spices and simmer for about 5 minutes.

Step 2: Cook pasta and preheat the oven.

Meanwhile, cook the pasta in boiling salted water until almost al dente and preheat the oven to 392 °F (200 °C).

Step 3: Refine the sauce, mix everything together and bake.

Stir the vegan crème fraîche into the sauce. Then mix in the spinach and parsley. Now drain the pasta and combine with the sauce. Then transfer everything into a baking dish, top with tofu feta and vegan cheese and bake for about 20-25 minutes until golden brown. Done!

Ingredient notes and recipe variations

• Vegetables: instead of mushrooms and/or spinach, you can add other sautéed vegetables such as savoy cabbage, kale, Brussels sprouts, broccoli, squash, carrots, eggplant, zucchini, etc.
• Protein: smoked tofu or legumes like cooked beans, chickpeas or lentils are a great addition for more protein.
• Béchamel sauce: you can also make this pasta bake with a dairy-free béchamel sauce according to my recipe for vegan lasagna.
• Cashew sauce: In my recipe for lentil zucchini lasagna you will also find instructions on how to make a super creamy cashew sauce, which is also suitable for this pasta bake.
• Cooking cream: Furthermore, there is the option that you simply use vegan cooking cream such as oat, almond or soy cream instead of vegetable broth + dairy-free crème fraîche.
• Vegan cheese: if you don’t want to buy a plant-based cheese alternative for gratinating, feel free to try my homemade vegan cheese.

How to store and reheat pasta bake?

You can store the leftover pasta bake covered in the refrigerator and then reheat it in the oven or microwave. If it’s too dry, simply drizzle with a little unsweetened plant milk.
