Ingredients for Crockpot French Onion Meatloaf
- 1.5 lbs (680 g) ground beef (or a mix of beef and pork)
- 1 cup French onion soup, divided (half for meat, half for topping)
- 1 cup shredded Swiss cheese (or sliced pieces, depending on preference)
- 1/2 cup breadcrumbs
- 1/4 cup milk
- 1 large egg
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tsp dried thyme or parsley (optional)
Optional Garnishes:
- Extra Swiss cheese melted on top
- Fresh parsley for color
Instructions
Prepare the Crockpot
Spray the inside of your crockpot with nonstick cooking spray or lightly grease with butter. This prevents sticking and ensures easy serving later.
Mix the Meatloaf
In a large mixing bowl, combine ground meat, half of the French onion soup, breadcrumbs, milk, egg, chopped onion, garlic, salt, pepper, and herbs (if using). Mix gently until combined—overmixing can make the meatloaf dense.
Stuff the Meatloaf with Cheese
Divide the meat mixture in half. Press the first half into the bottom of the crockpot, creating a flat layer. Layer the Swiss cheese evenly over the meat, then cover with the remaining meat mixture, sealing the edges around the cheese to prevent it from leaking during cooking.
Slow Cook
Pour the remaining French onion soup over the top of the meatloaf. Cover and cook on low for 6–7 hours or high for 3–4 hours. The meatloaf is done when the internal temperature reaches 160°F (71°C) and the meat is tender.
Optional: Melt Extra Cheese
For an extra cheesy finish, sprinkle additional Swiss cheese over the meatloaf in the last 15 minutes of cooking with the crockpot lid slightly open, allowing the cheese to melt without overcooking the meat.
Serve
Carefully lift the meatloaf from the crockpot using a spatula. Slice and serve warm, spooning any remaining French onion juices over each portion for added flavor.
Tips for Success
- Seal the cheese well: Make sure the Swiss cheese is fully enclosed by meat to prevent leaks.
- Use a large enough crockpot: The meatloaf should fit comfortably with a little space around the edges for even cooking.
- Check seasoning: Taste the French onion soup before adding to ensure it’s flavorful and adjust salt/pepper if needed.
- Avoid overcooking: Slow-cooked meatloaf can dry out if left too long—monitor the time based on your crockpot’s settings.
- Make ahead: Assemble the meatloaf in the morning and let it cook while you go about your day.
Common Troubleshooting
- Cheese leaks: Ensure meat completely covers the Swiss cheese and seams are pressed together.
- Meatloaf too dense: Mix the ingredients gently and use a combination of breadcrumbs and milk to keep it moist.
- Uneven cooking: Place the meatloaf in the center of the crockpot and avoid overpacking.
Variations and Customizations
- Cheddar or Gruyère: Swap Swiss for other melty cheeses for a different flavor profile.
- Mushroom lovers: Add sautéed mushrooms to the meat mixture for extra depth.
- Spicy twist: Incorporate a pinch of cayenne or smoked paprika for subtle heat.
- Mini meatloaves: Divide the mixture into small portions and cook as individual loaves for faster cooking and portion control.
Serving Suggestions and Pairing Ideas
Casual Serving: Serve slices directly from the crockpot with a spoonful of French onion sauce. Pair with mashed potatoes, roasted veggies, or buttered noodles for a comforting meal.
Dressed-Up Presentation: Plate slices individually, drizzle with remaining sauce, and sprinkle fresh parsley. Perfect for a cozy dinner or casual entertaining.
Beverage Pairings:
- Red wine like Merlot or Pinot Noir complements the rich flavors.
- Light beers or sparkling water work for casual family dinners.
- Serve alongside a crisp salad or roasted root vegetables for balance.
Storage and Make-Ahead Instructions
- Refrigerator: Store leftovers in an airtight container for 3–4 days. Reheat gently in the microwave or oven.
- Freezing: Wrap cooked meatloaf tightly and freeze for up to 2 months. Thaw overnight before reheating.
- Make-ahead: Assemble the meatloaf in the crockpot insert, cover, and refrigerate up to 12 hours before cooking.
