Servings

Serves: 6

Ingredients

Main Ingredients

  • 1 ½ lbs (680 g) ground beef

  • 1 medium onion, diced

  • 3 cloves garlic, minced

  • 6 medium potatoes, thinly sliced

  • 2 medium carrots, thinly sliced

  • 1 cup frozen peas (optional)

  • 1 can (10.5 oz) cream of mushroom soup

  • ½ cup beef broth

  • 1 cup shredded cheddar cheese (optional but delicious)

  • 1 tsp paprika

  • 1 tsp dried thyme

  • 1 tsp salt

  • ½ tsp black pepper

  • ½ tsp onion powder

  • ½ tsp garlic powder

Optional Add-ons

  • 1 cup sliced mushrooms

  • ½ cup sour cream (for extra creaminess)

  • Fresh parsley for garnish

Instructions

1. Prepare the beef

  1. In a skillet over medium heat, brown the ground beef with diced onion until no pink remains.

  2. Drain excess fat.

  3. Add garlic and cook 1 minute more.

  4. Season lightly with salt and pepper.

2. Mix the sauce

In a bowl, whisk together:

  • Cream of mushroom soup

  • Beef broth

  • Paprika

  • Thyme

  • Onion powder

  • Garlic powder

  • Remaining salt and pepper

(If using sour cream, mix it in here.)

3. Layer in the slow cooker

  1. Grease the slow cooker with cooking spray.

  2. Layer half of the sliced potatoes on the bottom.

  3. Add half of the carrots and peas.

  4. Add half of the cooked beef mixture.

  5. Spoon or pour half of the soup mixture over the top.

  6. Repeat a second layer: potatoes → veggies → beef → sauce.

  7. Top with shredded cheddar (either now or during the last 20 minutes for a melty top).

4. Cook

  • LOW: 6–7 hours

  • HIGH: 3–4 hours

Potatoes should be fork-tender and the casserole thick and creamy.

5. Serve

Scoop into bowls and garnish with fresh parsley if desired.

Notes

  • Slice potatoes evenly (⅛–¼ inch) for consistent cooking.

  • Yukon Gold or Russet potatoes work best for this recipe.

  • Ground turkey or chicken can be substituted, but use chicken broth instead of beef broth for better flavor balance.

  • Add more broth if you prefer a looser, stew-like dish.

Tips for Success

  • Pre-cooking beef is essential to avoid excess grease in the casserole.

  • For a crisp top, remove the slow cooker insert at the end and broil the top in the oven for 3–5 minutes.

  • Add vegetables like celery, corn, green beans, or bell peppers for more variety.

  • Don’t over-stir while cooking; layering ensures potatoes cook properly.

  • Keep the lid closed—lifting it prolongs cooking time by up to 20 minutes.

Q & A

Q: Can I make this recipe ahead of time?

Yes! Assemble the ingredients in the slow cooker insert, cover, refrigerate, and cook within 24 hours. Add about 30 minutes extra if cooking from cold.

Q: Can I freeze leftovers?

Absolutely. Freeze in airtight containers for up to 3 months. Thaw overnight and reheat in the microwave or oven.

Q: Can I use raw beef instead?

It’s not recommended. Pre-cooking prevents grease buildup and improves flavor.

Q: Can I make this dairy-free?

Use dairy-free cream of mushroom soup and skip the cheese or use a dairy-free alternative.

Q: How do I thicken it if it’s too watery?

Stir in a cornstarch slurry (1 tbsp cornstarch + 2 tbsp water) during the last 20 minutes of cooking.

Q: Can I turn it into a truly “one-pot meal”?

Yes—add more vegetables (corn, green beans, bell peppers) or even beans for extra nutrition and volume.
