How to Make:
Quick Overview
This crockpot meatloaf is easy because most of the work is simple mixing and layering. The slow cooker does the heavy lifting—producing a moist, fork-tender texture and concentrating flavors. Expect about 10 minutes active prep and 4 to 6 hours of slow cooking, depending on your heat setting. The standout elements are the rich French onion profile and the creamy melted Swiss that finishes the loaf.
Ingredients
- 2 pounds ground beef (80/20 for best flavor and moisture)
- 1 packet French onion soup mix (dry)
- 1 cup breadcrumbs (plain or seasoned)
- 1/2 cup milk (room temperature)
- 2 large eggs, beaten
- 1/4 cup ketchup
- 1 tablespoon Worcestershire sauce
- 1 cup caramelized onions (homemade or store-bought, chopped)
- 1 cup Swiss cheese, sliced (about 4–6 slices)
- Fresh thyme, for garnish (optional)
Directions
- In a large bowl, combine the ground beef, French onion soup mix, breadcrumbs, milk, beaten eggs, ketchup, and Worcestershire sauce. Mix with clean hands or a spoon until everything is evenly combined but do not overwork the meat.
- Line your crockpot with parchment paper or foil. This helps the meatloaf release easily later and makes cleanup much simpler.
- Press half of the meat mixture into the bottom of the crockpot, forming an even layer that reaches the sides.
- Layer the caramelized onions evenly over the meat, then add half of the Swiss cheese slices on top of the onions.
- Add the rest of the meat mixture on top, pressing gently to seal the edges so the filling stays inside while cooking.
- Cover the crockpot and cook on low for 6 hours or on high for 4 hours. The internal temperature should reach 160°F for ground beef.
- In the last 10 minutes of cooking, sprinkle the remaining Swiss cheese on top and cover until it melts and becomes gooey.
- Carefully lift the meatloaf from the crockpot using the parchment or foil, transfer to a cutting board, and garnish with fresh thyme before serving. Slice and serve warm.
What to Serve With:
- Mashed potatoes or creamy polenta to soak up the juices and cheese.
- Roasted green beans or garlic sautéed spinach for a bright, fresh contrast.
- A simple buttered dinner roll or crusty bread to wipe the plate clean.
- A crisp green salad with a tangy vinaigrette helps cut through the richness.
- For dessert, pair with a cozy fall treat like Apple Cream Cheese Bundt Cake with Caramel Pecan Topping for a sweet ending.
Top Tips for Perfecting:
- Use 80/20 ground beef: The extra fat keeps the meatloaf moist. If using leaner beef, add a tablespoon of olive oil or an extra egg to improve texture.
- Don’t overmix: Stir until ingredients are just combined to avoid a dense loaf.
- Make caramelized onions ahead: If you have time, slowly caramelize onions in a skillet until golden brown for the best flavor. Store-bought works in a pinch.
- Check doneness with a thermometer: For safety and perfect texture, aim for 160°F internal temperature.
- Avoid lifting the crockpot lid too often: Every peek releases heat and adds cooking time.
Storing and Reheating Tips:
- Refrigeration: Cool leftovers to room temperature, then store in an airtight container in the fridge for up to 3–4 days.
- Freezing: Slice the meatloaf into portions, wrap tightly in plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: For best results, reheat slices in a 350°F oven covered with foil for 10–15 minutes or until warmed through. You can also reheat in a skillet over medium-low heat with a splash of water or broth and a lid to retain moisture. Microwave reheating works for quick meals—cover and heat in 30-second intervals until hot.
FAQs
Can I use ground turkey or chicken instead of beef?
Yes. Ground turkey or chicken can be used, but they are leaner and may dry out. Add a tablespoon of olive oil or a small extra egg to keep the loaf moist, and check doneness carefully.
Do I have to caramelize onions from scratch?
No, you can use store-bought caramelized onions to save time, but homemade caramelized onions offer a richer, sweeter flavor.
Can I make this in the oven instead of a crockpot?
Yes. Form the loaf and bake in a 9×5-inch loaf pan at 350°F for 55–65 minutes, adding cheese in the last 10 minutes, until the internal temperature reaches 160°F.
How do I prevent the meatloaf from falling apart when serving?
Let the meatloaf rest for 10 minutes after cooking to firm up, and use the parchment or foil to lift it gently. Slicing with a sharp knife helps maintain shape.
Is this recipe freezer-friendly?
Absolutely. Freeze slices or the whole loaf (wrapped tightly) for up to 3 months. Thaw in the refrigerator before reheating.
