How to Cook French Onion Meatloaf with Swiss Cheese

• Blend Meat Mixture

Gently combine ground beef with breadcrumbs, milk, egg, French onion soup mix, Worcestershire sauce, and black pepper in a large bowl. Mix until ingredients are just incorporated.

• Shape and Prepare Crockpot

Form the meat mixture into a compact loaf and place it at the bottom of the crockpot, ensuring it sits evenly.

• Caramelize Onions

Heat butter in a skillet over medium temperature. Cook sliced onions, stirring occasionally, until they turn golden and develop a rich, sweet flavor, approximately 10-12 minutes.

• Layer and Season

Spread the caramelized onions uniformly over the meatloaf. Pour beef broth around the meat and sprinkle thyme for additional flavor.

• Slow Cook

Cover the crockpot and cook on low setting for 6-8 hours or high setting for 3-4 hours, until the internal temperature reaches 160F.

Ten minutes before serving, layer Swiss cheese slices over the meatloaf. Cover and allow cheese to melt completely.

Carefully transfer the meatloaf to a serving plate. Slice and garnish with caramelized onions and broth as a delicious gravy.

Tips That Add Bold Flavor to This Meatloaf

• Learn how to perfectly nail this French onion meatloaf every single time with these pro tips.
• Avoid dry meatloaf by using a mix of ground beef with slightly higher fat content (80/20) which keeps the dish juicy and tender during long slow cooking.
• Swap traditional breadcrumbs with gluten-free alternatives like almond flour or gluten-free panko to make the recipe celiac-friendly without losing texture or flavor.
• Replace breadcrumbs with finely crushed pork rinds or ground almonds to reduce carbohydrate content while maintaining the meatloaf's classic structure and taste.
• Assemble the entire meatloaf the night before, store covered in the refrigerator, and pop it into the crockpot next morning for an effortless dinner with minimal morning preparation.

Serve Crockpot Meatloaf with Mashed Potatoes

• Comfort Meal Pairing: Serve this hearty meatloaf alongside creamy mashed potatoes or buttery egg noodles to soak up the delicious broth and complement the rich flavors.
• Vegetable Companions: Roast some crisp green beans or honey-glazed carrots as a fresh, colorful side that balances the meatloaf's savory profile and adds nutritional variety.
• Bread Basket Bonus: Include warm crusty bread or garlic toast to help guests mop up the extra caramelized onion gravy, turning each bite into a delightful flavor experience.
• Wine and Dine: Pair this classic comfort dish with a medium-bodied red wine like Pinot Noir or Merlot, which will enhance the meatloaf's deep, rich taste and complement its French-inspired elements.

Keep Meatloaf Moist and Delicious After Cooking

• Refrigerate leftover meatloaf in airtight containers within two hours of cooking, keeping it fresh for up to 4 days. Cool the dish completely before storing to prevent bacterial growth.
• Wrap individual slices or the entire meatloaf tightly in plastic wrap, then aluminum foil. Freeze for up to 3 months, ensuring maximum flavor retention when properly sealed.
• Warm refrigerated meatloaf in the microwave at 50% power, adding a splash of beef broth to maintain moisture. Alternatively, reheat in a covered oven dish at 350°F for 15-20 minutes until internal temperature reaches 165°F.
• Slice the meatloaf into portions immediately after cooling. Pack with caramelized onions and a small container of broth for lunch, creating convenient grab-and-go meals that stay delicious and moist.

FAQs

• Why use a crockpot for this meatloaf?

The crockpot helps keep the meatloaf incredibly moist and tender by cooking it slowly with low, consistent heat. It also allows the flavors to develop deeply and prevents the meat from drying out.

• Can I use ground turkey instead of beef?

Yes, you can substitute ground turkey, but keep in mind that it has less fat, which might make the meatloaf slightly less juicy. Consider adding an extra tablespoon of Worcestershire sauce or a bit more milk to maintain moisture.

• How do I know the meatloaf is fully cooked?

Use a meat thermometer to check that the internal temperature reaches 160F (71C). This ensures the meat is safe to eat while remaining juicy and flavorful. Avoid cutting into the meatloaf too early to prevent losing precious moisture.

• What if I don't have French onion soup mix?

You can replace it with a combination of dried onion powder, salt, and beef bouillon powder. This will help maintain the rich onion flavor that’s key to this recipe’s profile.
