Crockpot French Onion Meatloaf: A Comfort Food Classic With a Savory Twist


 

How to Make Crockpot French Onion Meatloaf

1. Prepare the Onions

  1. In a skillet, melt butter over medium heat.

  2. Add sliced onions and cook slowly until golden and soft (10–15 minutes).

  3. Set aside half for mixing into the meatloaf and half for the topping.

2. Mix the Meatloaf

  1. In a large bowl, combine:

    • ground beef

    • crushed crackers

    • eggs

    • milk

    • French onion soup mix

    • diced or caramelized onions

    • garlic powder

    • thyme

  2. Mix gently—overworking the meat can make it dense.

  3. Stir in shredded cheese if using.

  4. Shape the mixture into a loaf.

3. Assemble in the Crockpot

  1. Place two long strips of foil or parchment in the bottom of the crockpot to help lift the meatloaf out later (optional but helpful).

  2. Set the meatloaf inside.

  3. Pour the remaining caramelized onions, beef broth, and Worcestershire sauce over the top.

4. Slow-Cook to Perfection

  • Cook on LOW for 6–7 hours or HIGH for 3–4 hours.

  • If you prefer a thicker sauce, stir in the cornstarch slurry during the last 30 minutes.

5. Optional Cheese Finish

For an authentic French onion–style finish:

  • Sprinkle shredded Gruyère or Swiss over the meatloaf.

  • Cover for 10 minutes to melt.

Serving Ideas

Serve slices with:

  • creamy mashed potatoes

  • roasted vegetables

  • buttered noodles

  • crusty bread for soaking up the sauce

The combination of savory gravy and tender beef makes this dish unforgettable.

Tips for Best Results

  • Choose the right beef: A little fat keeps the meatloaf moist in the crockpot.

  • Don’t skip the onions: Their sweetness is the heart of French onion flavor.

  • Let it rest before slicing: 5–10 minutes helps the loaf hold its shape.

  • Add cheese inside and on top for richness: Gruyère, Swiss, or provolone work beautifully.
