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!
