Shopping List
- 1.5 pounds ground beef (85% lean is ideal)
- 1 medium yellow onion, diced
- 3 garlic cloves, minced
- 1 can (15 oz) diced tomatoes, undrained
- 1 can (10–15 oz) tomato sauce or crushed tomatoes
- 1 can (15 oz) kidney beans, drained and rinsed
- 1 can (15 oz) pinto beans or black beans, drained and rinsed
- 1 can (15 oz) whole-kernel corn, drained (or 1.5 cups frozen corn)
- 4 cups thinly sliced russet or Yukon Gold potatoes (about 3–4 medium)
- 1 cup beef broth (low sodium)
- 1 cup shredded cheddar cheese (or a blend)
- 2 tablespoons tomato paste (optional, for richness)
- 2 teaspoons chili powder
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- 1/2 teaspoon dried oregano
- Salt and black pepper, to taste
- 1 tablespoon olive oil (for browning)
- Fresh parsley or green onions, chopped (optional, for garnish)
- Sour cream or hot sauce (optional, for serving)
How to Make It
- Prep the potatoes: Wash and thinly slice the potatoes into rounds, about 1/4 inch thick. No need to peel unless you prefer.
- Brown the beef: Heat olive oil in a large skillet over medium-high heat. Add ground beef and cook, breaking it up, until no longer pink.
Drain excess fat.
- Cook the aromatics: Add diced onion and minced garlic to the skillet with the beef. Sauté 3–4 minutes until the onion softens.
- Season it up: Stir in chili powder, cumin, smoked paprika, oregano, salt, and pepper. Add tomato paste if using and cook 1 minute to bloom the flavors.
- Add tomatoes: Pour in the diced tomatoes and tomato sauce.
Simmer 2–3 minutes. Taste and adjust seasoning.
- Layer the slow cooker: Grease the slow cooker insert lightly. Place half the potato slices on the bottom.
Top with half the corn and half the beans.
- Add the beef mixture: Spoon half of the beef-tomato mixture over the potatoes and beans. Repeat the layers with the remaining potatoes, corn, beans, and beef.
- Add broth: Pour the beef broth around the edges so it settles evenly. This helps the potatoes cook tender.
- Cook: Cover and cook on Low for 6–7 hours or High for 3–4 hours, until the potatoes are fork-tender.
- Finish with cheese: Sprinkle shredded cheddar over the top.
Cover and cook 10–15 more minutes until melted and bubbly.
- Serve: Let it rest 5–10 minutes to set. Spoon into bowls and garnish with parsley or green onions. Add sour cream or a dash of hot sauce if you like.
How to Store
- Refrigerate: Cool completely, then store in airtight containers for up to 4 days.
- Freeze: Portion into freezer-safe containers and freeze up to 3 months.
Thaw overnight in the fridge.
- Reheat: Warm gently on the stovetop over low heat or in the microwave, stirring occasionally. Add a splash of broth if it seems thick.
Health Benefits
- Protein and iron: Ground beef provides protein for muscle health and iron for energy and focus.
- Fiber-rich beans: Kidney and pinto beans add fiber, which supports digestion and helps you stay full longer.
- Potassium and vitamin C: Potatoes offer potassium for heart health and fluid balance, plus vitamin C for immune support.
- Customizable sodium: Using low-sodium broth and rinsing canned beans keeps salt in check.
- Balanced meal: Carbs, protein, and fats work together for steady energy, especially when served with a side salad or steamed veggies.
What Not to Do
- Don’t skip draining the beef fat: Excess grease can make the casserole heavy and greasy.
- Don’t slice potatoes too thick: Thick slices won’t cook through evenly in the slow cooker.
- Don’t add cheese too early: It will overcook and turn rubbery. Add at the end for the best melt.
- Don’t forget seasoning: Taste the beef mixture before layering.
Under-seasoned sauce leads to a bland dish.
- Don’t overfill the slow cooker: Leave at least 1 inch of space at the top for proper heat circulation.
Variations You Can Try
- Turkey or chicken: Swap ground beef for lean ground turkey or chicken for a lighter version.
- Veggie-forward: Add bell peppers, zucchini, or mushrooms with the onions for extra vegetables.
- Spicy kick: Use hot diced tomatoes with green chilies, add chipotle in adobo, or stir in sliced jalapeños.
- Sweet potato twist: Replace some or all of the potatoes with sweet potatoes for a subtle sweetness and more vitamin A.
- Dairy-free: Skip the cheese or use a dairy-free melt. The casserole is still rich and satisfying.
- Tex-Mex style: Add a packet of taco seasoning (or extra cumin, chili powder, and coriander), and finish with cilantro and lime.
- Crispy topper: Sprinkle crushed tortilla chips or fried onions over the melted cheese just before serving for crunch.
FAQ
Can I make this without pre-browning the beef?
You can, but it’s not ideal. Browning develops flavor, improves texture, and lets you drain excess fat.
If you must skip it, use very lean beef and add extra spices.
What size slow cooker should I use?
A 6-quart slow cooker works best. A 5-quart can work if you pack it carefully, but avoid overfilling. For larger batches, use an 8-quart.
Can I use canned sliced potatoes?
Yes, but add them later since they’re already cooked.
Layer everything else first and tuck canned potatoes in the last 2 hours on Low so they don’t turn mushy.
How do I keep the potatoes from turning gray?
Slice them just before layering. If prepping ahead, submerge sliced potatoes in cold water with a splash of vinegar or lemon juice, then drain and pat dry before assembling.
Is there a way to make it gluten-free?
It’s naturally gluten-free if you use gluten-free broth and spices. Always check labels on broth, tomato products, and spice blends to be sure.
Can I cook it in the oven instead?
Yes.
Layer everything in a greased 9×13-inch baking dish, cover tightly with foil, and bake at 375°F (190°C) for 60–75 minutes, until potatoes are tender. Uncover, add cheese, and bake 10 more minutes.
Why is my casserole watery?
Some tomatoes and potatoes release liquid. To thicken, remove the lid for the last 20–30 minutes on High or stir in a slurry of 1 tablespoon cornstarch mixed with 1 tablespoon cold water.
Can I use sausage instead of beef?
Absolutely.
Brown mild or spicy sausage and proceed with the recipe. You may want to reduce added salt since sausage is often seasoned.
What should I serve with it?
A simple green salad, steamed green beans, or roasted broccoli keeps the meal balanced. Warm cornbread or crusty bread also pairs nicely.
How long can it sit on Warm?
Up to 2 hours is fine.
Stir once or twice to prevent sticking, and add a splash of broth if it thickens too much.
