Are you aware that more than 70 parents in United States cook with slow cookers at least once a week to reduce time and stress at mealtime? As a working mom with family responsibilities and what feels like an infinite to-do list, I get it. And that’s precisely why I created this Slow Cooker Ground Beef Dorito Casserole — because sometimes you just want comfort food that does most of the work for you.

This casserole is when I want to avoid the dreaded “What’s for dinner?” It’s a hybrid of the two things we love most: the cheesy taco flavors we’ve consumed by the vat, plus a layer of crunchy Doritos that could easily be invented in a lab, kneaded into a paste and slowly melted into a single onefied Tex-Mex Molotov cocktail. It’s based on a potluck dish my sister made years ago — that kind of cheesy, slightly trashy casserole that evaporates before you’ve even had time to grab a plate.

But this version has a twist: It’s all made in the slow cooker, which means it’s hands-free, and great for batch cooking. Whether you’re trying to feed teens, cater to picky eaters or just feed your inner snack-loving soul, this Slow Cooker Ground Beef Dorito Casserole is the hero your weeknight desperately needs.

2 cups (200g) grated cheddar cheese — Sharp or mild, your call.

1 bag (9.75 oz / 275g) Nacho Cheese Doritos~ – Slightly crushed.

1/2 cup (120ml) milk

Optional Add-ins:

1/2 cup black beans (drained and rinsed) — for added fiber.

1/2 c corn kernels – Frozen or canned (drained)

1 jalapeño, thinly sliced — If you want heat.

Timing

Prep Time: 15 minutes

Cook Time: 3–4 hours on low (or 2 hours on high)

Total Time: About 4 hours 15 minutes

Active time: 15 minutes | Passive time: 4 hours

💡 This recipe saves you 20 to 30 percent of the active cooking time of traditional baked casseroles.

Step-by-Step Instructions

Step 1: Brown the Ground Beef

Brown the ground beef with onions in a skillet over medium heat until no pink remains. Drain excess grease.

Pro Tip: Sprinkle the taco seasoning onto the beef while it’s still a little bit wet — this helps the spices bloom and stick more.

Step 2: Combine the Sauce

Mix Rotel, cream of mushroom soup, milk and sour cream in a medium bowl. Add the seasoned beef mixture and stir in.

You should smell that distinctive Tex-Mex tang from the tomatoes and seasoning mix!

Step 3: Layer the Casserole

Grease your slow cooker insert with cooking spray. 1/3 Crushed Doritos Layer 1/3 beef mixture and then 1/3 shredded cheese. Repeat twice more.

Top with cheese at the end for that golden, melty end.

Step 4: Slow Cook

Cover and cook on low for 3–4 hours, or on high for 2 hours. Don’t lift the lid while it’s cooking — you want to keep that cheesy heat in!

You will know it is done once the edges are bubbling and the cheese has completely melted.

Step 5: Garnish and Serve

Garnish with chopped green onions, fresh cilantro or a dollop of guacamole before serving.

Chef’s Notes and Technical Tips

Make layers: The less hot Doritos are at the top and bottom of the pile, the more crunch they will retain.

Cheese choices: Pre-shredded cheese is fine, but shredding your own makes for a smoother melt since there are fewer anti-caking agents.

Slow cooker size: Use a 6-quart slow cooker or larger so the soup doesn’t overflow.

Temperature & Doneness

Food safety temperature is 165°F (74°C).

If it’s too soupy, let it sit uncovered for 15 minutes after cooking to thicken.
