Ingredients You’ll Need

The magic of Crockpot Mexican Casserole is how it transforms such simple, everyday ingredients into something truly crave-worthy. Each addition brings its own personality—color, kick, creaminess, or just that irresistible heartiness you want in a casserole.

• Extra-virgin olive oil: Starts the dish off with a touch of richness and helps brown the meat beautifully.
• Ground turkey (or chicken): A lean, protein-packed base; try 93% lean for great flavor and a lighter texture.
• Yellow onion: Diced onion brings a naturally sweet, aromatic depth to the casserole.
• Uncooked quinoa: Quinoa soaks up the sauces and adds a tender, slightly nutty texture you’ll love.
• Red enchilada sauce: The backbone of classic Mexican flavor with just the right amount of spice.
• Black beans: Earthy, plump, and perfect for extra protein and fiber; don’t forget to rinse and drain!
• Fire-roasted diced tomatoes: These give a subtle smokiness that pairs so well with the other bold flavors.
• Corn kernels: Pops of sweetness and color; use fresh or frozen for convenience.
• Red bell pepper: Adds crunch and helps brighten every bite with a hint of sweetness.
• Green bell pepper: Offers an extra layer of fresh, slightly grassy flavor.
• Chili powder: The main spice player that brings gentle warmth without overwhelming heat.
• Ground cumin: Adds that deep, earthy, crave-worthy aroma you recognize from your favorite Mexican recipes.
• Garlic powder: Gives the casserole a well-rounded, savory backbone.
• Water: Keeps everything moist and helps the quinoa cook perfectly.
• Shredded Mexican blend cheese: Melts into gooey goodness; use half for richness throughout and half for that golden baked top.
• For serving – cilantro, avocado, green onion, sour cream/Greek yogurt: Toppings that add freshness, creaminess, and a final pop of flavor!

How to Make Crockpot Mexican Casserole

Step 1: Brown the Ground Turkey and Onion

Heat your olive oil in a large skillet or Dutch oven over medium-high heat. Add the ground turkey and diced onion, cooking together while you break up the meat. Sizzle them for about five minutes until the turkey loses all that pink and the onion is tender. This quick step seals in flavor while keeping your Crockpot Mexican Casserole juicy and rich from the very beginning. Transfer the mixture to your slow cooker so you’re ready for the next round of vibrant flavors.

Step 2: Add the Veggies, Spices, and Quinoa

Into the slow cooker, pile in the uncooked quinoa, red enchilada sauce (yep, use both cans!), drained black beans, fire-roasted tomatoes with their juices, sweet corn, diced red and green bell peppers, chili powder, cumin, garlic powder, and that half cup of water. Stir everything together until so many colors and textures start mingling—it’s already looking like a party in the pot!

Step 3: Slow Cook to Perfection

Now comes the most hands-off (and most rewarding) part: pop on the lid and let your Crockpot Mexican Casserole cook. Go for high for about 2 and a half to 3 hours, or set it on low for 5 to 6 hours if you want to set it and forget it. When it’s done, the quinoa will be tender and most of the liquid absorbed—your kitchen will smell like a Tex-Mex dream!

Step 4: Stir in Cheese and Finish Cooking

Lift the lid, give everything a gentle but thorough stir, and taste to see if you want to tweak the seasonings. Stir in half of the shredded Mexican blend cheese so it melts right into the casserole, making every bite stretchy and creamy. Scatter the rest of the cheese over the top, cover, and cook on high for about 10 to 15 minutes until the cheese is bubbly and irresistible.

Step 5: Serve with Fresh Toppings

Spoon the Crockpot Mexican Casserole into bowls while it’s hot and steamy. Let everyone pile on fresh cilantro, creamy avocado, chopped green onion, and a dollop of sour cream or Greek yogurt. The combination of melty, spicy, fresh, and cool is simply unbeatable!

Garnishes

Let your family or guests have fun personalizing their bowls!

Side Dishes

Since Crockpot Mexican Casserole is a complete meal all by itself, you don’t need much on the side—but a crisp green salad with a citrusy vinaigrette or some warm tortilla chips for scooping adds a wonderful crunch.
