The Full French Onion Meatloaf Recipe
Ingredients
- 2 tbsp olive oil
- 2 lbs yellow onions, thinly sliced
- 1/8 tsp baking soda
- 1/2 cup unseasoned dried breadcrumbs
- 1/2 cup whole or 2% milk
- 2 cloves garlic, minced
- 2 tsp Worcestershire sauce
- 1 1/2 tsp kosher salt
- 1/4 tsp freshly ground black pepper
- 2 lbs ground beef
- 2 large eggs, lightly beaten
- 1 cup shredded Gruyère cheese (about 3 oz)
Instructions
- Preheat your oven to 350°F (175°C) and line a 9×5-inch loaf pan with aluminum foil to make for easy removal later.
- In a large pot over medium-high heat, add olive oil and sliced onions along with the baking soda. This will help caramelize the onions quickly. Cook for about 15 minutes, stirring occasionally to prevent sticking.
- Continue cooking the onions until they turn deep golden-brown, which should take around 10-15 minutes more. The rich color will enhance the flavor of your meatloaf.
- In a large bowl, mix the breadcrumbs with the milk and let it sit for a few minutes. This helps the breadcrumbs absorb moisture and keep the meatloaf tender.
- Add the caramelized onions (allow them to cool slightly), minced garlic, Worcestershire sauce, salt, and black pepper to the breadcrumb mixture. Combine everything well.
- Next, add ground beef and eggs to the bowl. Using your fingers, gently mix the ingredients together, being careful not to overmix to keep the texture light.
- Transfer the mixture into the prepared loaf pan, pressing it down evenly. This ensures that it cooks uniformly.
- Bake in the preheated oven for 55-60 minutes until the internal temperature reaches 165°F (74°C). Use a meat thermometer for accuracy!
- Remove the meatloaf from the oven and switch to the broil setting. Sprinkle the reserved caramelized onions and shredded Gruyère cheese on top.
- Broil for about 2 minutes, watching carefully until the cheese is melted, bubbly, and slightly browned.
- Let the meatloaf cool in the pan for 15 minutes before slicing. This helps it set and makes for cleaner slices.
Serving Suggestions and Variations for French Onion Meatloaf
This delicious meatloaf pairs wonderfully with creamy mashed potatoes and steamed green beans or a fresh side salad. For a twist, consider serving it on a toasted bun as a meatloaf sandwich.
