Prep and Cook Time
- Preparation: 20-30 minutes
- Cooking: 4-6 hours on low or 2-3 hours on high
Yield
- Serves 6-8 hearty portions
Difficulty Level
- Easy to Medium – ideal for both beginners and seasoned cooks
Ingredients
- 1 pound ground beef (lean, preferably 85%)
- 1 cup diced onions, finely chopped
- 2 cloves garlic, minced
- 1 cup sliced mushrooms (optional for added depth)
- 2 cups peeled and diced potatoes (Yukon Gold or red potatoes work best)
- 1 cup baby carrots
- 1 can (14 oz) diced tomatoes, undrained
- 1 cup shredded cheddar cheese, divided
- 1 cup frozen peas
- 1/2 cup sour cream
- 1/2 cup beef broth or vegetable broth
- 1 tablespoon Worcestershire sauce
- 2 teaspoons smoked paprika
- 1 teaspoon dried thyme
- Salt and freshly ground black pepper, to taste
- 2 tablespoons olive oil
- Fresh parsley for garnish (optional)
Instructions
- Heat olive oil in a large skillet over medium heat. Add diced onions and sauté until translucent, about 5 minutes, stirring occasionally to prevent burning.
- Add minced garlic and sliced mushrooms; cook until mushrooms are golden and fragrant, approximately 4 minutes.
- Add ground beef to the skillet, breaking it apart with a wooden spoon. Cook until browned and no longer pink, about 7 minutes. Season with salt, pepper, and smoked paprika during this process.
- Transfer the sautéed mixture to the slow cooker. Add diced potatoes, baby carrots, diced tomatoes with their juices, frozen peas, Worcestershire sauce, dried thyme, and beef broth.
- Gently stir to combine ingredients evenly, then cover and cook on low for 5 to 6 hours, or on high for 3 hours, until vegetables are tender and flavors meld beautifully.
- About 30 minutes before serving, stir in sour cream and half of the shredded cheddar cheese until creamy and well blended.
- Sprinkle the remaining cheese on top, cover, and continue cooking until cheese melts, about 10 minutes.
- Garnish with freshly chopped parsley for a burst of color and freshness just before serving.
Chef’s Notes & Tips for Success
- Swap proteins: Try shredded chicken or turkey for a lighter version, or keep it vegetarian by substituting beans and extra mushrooms for the meat.
- Layer flavors: Use caramelized onions or roasted garlic for a deeper, sweeter aroma that transforms the base of your casserole.
- Make ahead: Assemble all ingredients in the slow cooker insert and cover tightly with plastic wrap. Refrigerate overnight, then cook the following day for a convenient meal prep solution.
- Ensure even cooking: Avoid overfilling the slow cooker to allow heat circulation; filling it 2/3 full is ideal.
- Thicken your sauce: If the casserole appears watery near the end, stir in a cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon water) and cook uncovered for 15 minutes.
Serving Suggestions
Present your slow cooker casserole in wide, shallow bowls to showcase the vibrant colors and textures. Garnish with freshly chopped parsley or chives and a dollop of sour cream for a rich finish. Pair with a crisp green salad or crusty garlic bread to balance the hearty richness. For an extra touch, sprinkle toasted breadcrumbs or crushed crackers on top just before serving for that irresistible crunch.

This method not only softens tough cuts of meat but also lets spices and herbs fully infuse, creating a rich, layered taste experience.
Q3: Can I prepare these casseroles ahead of time?

A4: Many slow cooker casserole recipes are adaptable. Whether you’re vegetarian, gluten-free, or watching your calories, you can easily swap ingredients to suit your dietary needs without sacrificing flavor or comfort.

Q8: What’s the easiest way to add a crispy top to a slow cooker casserole?
