Are you looking for a new vegetarian slow cooker meal? This delicious, creamy Crockpot Quinoa with Mushrooms is it! It's rich and creamy, and the quinoa and white beans pack over 20 grams of protein.  

The secret ingredient to create a creamy, almost risotto-like slow cooker quinoa dish is reduced-fat cream cheese. It adds a rich, indulgent texture without the heaviness, and when paired with earthy roasted mushrooms, bright green onions, and salty Parmesan—yum!

Plus, you can easily toss in extra veggies like spinach, kale, Swiss chard, or red bell pepper for even more flavor.

To make this dish, just toss quinoa, white beans, garlic, and broth into the slow cooker. In a few hours, you'll have creamy, flavor-packed goodness. It’s also one of those dishes that somehow tastes even better the next day, making it perfect for leftovers. And if your family isn’t into mushrooms? Just swap in your favorite roasted veggies

What's in Slow Cooker Garlic Mushroom Quinoa?

This is just a brief list of what's in this recipe! For the full list of recipe ingredients, check out the recipe card:

  • Quinoa: This protein-packed grain gives the dish a hearty base with a slightly nutty flavor and a fluffy, risotto-like texture.
  • Mixed Mushrooms: Roasting the mushrooms enhances their earthy, umami flavor and adds a meaty texture. Feel free to swap in other roasted veggies. 
  • Cream Cheese: Reduced-fat cream gives you a velvety texture while still keeping things light! You could also use Greek yogurt, but it will have more tang or use diary-free cream cheese for a vegan option. 
  • Parmesan Cheese: This cheese adds a salty, nutty kick that takes the dish to the next level. Freshly grated Parmesan is worth the effort. It melts more evenly. Swap in nutritonal yeast for a vegan option. 

What mushrooms work best for this recipe?

A mix of mushrooms adds the best depth of flavor. Cremini mushrooms give a hearty, earthy flavor; shiitake mushrooms add a meaty texture; and oyster mushrooms bring a more delicate, slightly sweet note. Don't be afraid to mix and match based on what's available.

How to Make Mushroom Quinoa in the Slow Cooker

Here's a basic understanding of how to make this recipe:

1. Prep the Quinoa and Beans

Add the quinoa, white beans, vegetable broth, minced garlic, and seasonings to your slow cooker. Stir well to ensure the garlic and seasonings are evenly distributed.

Pro Tip: If you want a richer, nuttier flavor, toast the quinoa in a dry skillet over medium heat for a few minutes before adding it to the slow cooker. 

2. Slow Cook Until Tender

Cover the slow cooker and let everything simmer until the quinoa is tender and the beans have absorbed the flavors.

3. Roast the Mushrooms

While the quinoa cooks, spread the mushrooms on a baking sheet, drizzle with olive oil, and season with salt and pepper. Roast until they’re golden brown and slightly crispy on the edges. Roast the mushrooms with some fresh herbs like thyme or rosemary for extra flavor. 

Pro Tip: Don’t overcrowd the pan. Spreading the mushrooms in a single layer helps them roast instead of steam.

4. Make It Creamy

Stir the cream cheese and Parmesan into the cooked quinoa until it’s smooth and creamy. Add warm broth a little at a time until you get that risotto-like texture.

Pro Tip: Use room-temperature cream cheese for easier mixing and a silkier texture.

5. Finish and Serve

Stir in the fresh herbs and a squeeze of lemon juice to brighten the flavors. Top each serving with the roasted mushrooms and some extra Parmesan if you like.

Do I have to roast the mushrooms?

If you’re short on time, skip roasting the mushrooms separately and add them directly to the slow cooker. While you’ll miss out on some caramelization, the mushrooms will still infuse the quinoa with earthy goodness.

How do I make this recipe ahead of time?

Chop the mushrooms and herbs and measure out your ingredients the night before. Roast the mushrooms and simply reheat when it's time to serve in a hot skillet.

In the morning, just toss everything into the slow cooker, and you're ready to go. This is easy, stress-free meal prep at its finest!

Recipe Ideas

This is one of those recipes that's easy to customize and make your own.

  • Broth: Change up the flavor slightly by using chicken or beef broth in place of the vegetable broth.
  • Mushrooms: Reach for a different type of mushroom or add a variety of mushrooms.
  • Greens: Chop up some kale to add greens to the dish, or stir in some fresh spinach right before serving.
  • Tomatoes: Add some extra flavor with a can of drained diced tomatoes. Add them once the quinoa has finished cooking. This recipe is also delicious with some sundried tomatoes. 
  • Toppings: Top the entire dish with fresh basil or parsley. Swap out the Parmesan for creamy goat cheese or punchy feta cheese.
  • Veggies: Add extra veggies when roasting the mushrooms. Favorites include chopped onions, asparagus, zucchini, or green beans. Frozen peas can also be added to the slow cooker. 
  • Spices: Play around with the herbs and spices to change up the flavor. You can make this with almost any spices or herbs you love.

Frequently Asked Questions

Here are some quick questions about making this recipe:

To store the slow cooker quinoa with roasted mushrooms, let it cool completely before transferring it to an airtight container. It will stay fresh in the refrigerator for up to 4 days. 

To reheat, warm it in a skillet over medium heat with a splash of vegetable broth to restore its creamy texture, or microwave it in 30-second intervals, stirring in between.

 

Yes, but with a few caveats. The texture of the quinoa will remain intact, but the mushrooms may become slightly softer when thawed. To freeze, let the dish cool completely, then store it in an airtight container for up to 2 months. Thaw overnight in the fridge and reheat with a little extra broth to refresh the texture.

1

Add the quinoa, white beans, vegetable broth, garlic, salt, and pepper to the slow cooker. Cover and cook on low for 3-4 hours until tender.

2

About 30 minutes before the quinoa is done, preheat the oven to 425. Add the mushrooms to a large baking sheet. Drizzle with olive oil, salt, and pepper. Toss to coat. Roast the mushrooms for 15-20 minutes until golden brown.

3

When the quinoa is done, stir in the cream and Parmesan cheese. It will be thick and a little sticky. Slowly add extra vegetable broth, starting with 1/2 cup. Continue to add vegetable broth until it is creamy, like risotto. Usually I need around 1 cup total but you may need more. Stir in the basil, parsley, and green onions. Season well with salt and pepper. Serve with roasted mushrooms, fresh Parmesan cheese, fresh lemon, and fresh herbs.

Hi- this sounds like a great recipe. I’m confused about the amount of broth to use, though. Do I start with just .5 cups of warm broth and then up to an additional 1.5 cups warm broth after I add the cheese? That doesn’t sound right….thanks in advance.

Start by adding about 1/2 cup and then continue to stir in more broth until it is nice and creamy, with a risotto like texture. Normally I only need about 1 cup, but depending on the quinoa, sometimes you may need a bit more. Hope that helps and that you enjoy the recipe.
