Ingredients

  • 1 lb ground beef
  • 1 small yellow onion diced
  • 2 garlic cloves minced
  • 2 tsp smoked paprika
  • 1 tsp dried thyme
  • ½ tsp salt
  • ¼ tsp black pepper
  • 3 medium potatoes peeled and thinly sliced
  • 1 can 15 oz fire-roasted diced tomatoes, drained
  • 1 cup frozen corn
  • 1 can 15 oz white beans or pinto beans, drained and rinsed
  • 3/4 cup sour cream
  • 1/2 cup whole milk
  • 1 ½ cups shredded cheddar cheese divided
  • 1/4 cup chopped pickled jalapeños optional, for kick
  • 1/2 tsp liquid smoke optional, for that “campfire” flavor

Instructions

  • Brown the meat: In a skillet over medium heat, cook ground beef with diced onion and garlic until browned. Stir in paprika, thyme, salt, and pepper. Drain excess fat.
  • Mix creamy layer: In a bowl, stir together sour cream, milk, and 1cup cheddar cheese. Add jalapeños and liquid smoke if using.
  • Layer in slow cooker: • Start with a layer of potatoes. • Spoon over half of the beef mixture. • Add half the tomatoes, corn, and beans. • Dollop and spread half of the creamy mixture. • Repeat the layers one more time, finishing with the rest of the cheese on top.
  • Cook: Cover and cook on low for 6–7 hours or high for 3–4 hours, until potatoes are fork-tender and everything is bubbly.
  • Serve: Let rest for 10 minutes before serving. Top with chopped scallions or fresh parsley if you want a pop of color.

Notes

Q: Can I use canned sliced potatoes instead of fresh?

A: Yes, but the texture will be softer. Drain them well and reduce cooking time slightly.

Q: What can I substitute for sour cream?

A: Plain Greek yogurt or a dairy-free alternative works great.

Q: Can I make this vegetarian?

A: Yes. Omit the beef and double the beans or use lentils for protein.

Q: Can I freeze leftovers?

A: Yes. Cool completely, portion into containers, and freeze for up to 2 months. Thaw overnight and reheat.

Q: How spicy is it with jalapeños?

A: Mild to medium. For less spice, omit. For more heat, keep seeds or add hot sauce.
