Ingredients for French Onion Meatloaf
Here’s what you’ll need to bring this savory masterpiece to life. Choose quality ingredients for the best results!
- 1 1/2 pounds ground beef: Use 80/20 for juicy, flavorful meatloaf.
- 1 cup breadcrumbs: Plain or Italian-style work well. Panko adds a lighter texture.
- 1/2 cup milk: Whole or 2% keeps the meatloaf moist. Non-dairy works in a pinch.
- 2 large onions, thinly sliced: Yellow onions are classic, but you can use white or sweet onions for a different flavor note.
- 2 cloves garlic, minced: Fresh garlic adds depth and warmth.
- 1 egg, beaten: Acts as a binder, holding everything together.
- 2 tablespoons Worcestershire sauce: For a savory, umami kick.
- 1 tablespoon Dijon mustard: Adds a subtle tang and complexity.
- 1 teaspoon dried thyme: Earthy, aromatic, and classic in French cuisine.
- 1/2 teaspoon salt & 1/2 teaspoon black pepper: Season to taste.
- 2 tablespoons butter: For caramelizing the onions—don’t skimp!
- 1/4 cup beef broth: Deglazes the pan and intensifies the flavor.
- 1 cup shredded Gruyère or Swiss cheese: Gruyère is traditional, but Swiss is a good substitute.
Ingredient Tips:
- For extra richness, try mixing in a bit of ground pork with the beef.
- Use freshly shredded cheese for the best melt and flavor.
- Gluten-free? Substitute with gluten-free breadcrumbs.
Step-by-Step Instructions
1. Caramelize the Onions
Time: 20–25 minutes
- Melt 2 tablespoons butter in a large skillet over medium heat.
- Add the thinly sliced onions and cook, stirring frequently. The onions will soften, then gradually turn golden and sweet.
- After about 20 minutes, stir in 1/4 cup beef broth to deglaze the pan, scraping up any flavorful brown bits. Continue to cook until the liquid is absorbed and onions are deeply caramelized.
- Set aside to cool slightly before adding to the meat mixture.
Tip: Don’t rush the onions! Low and slow brings out the best flavor.
2. Prepare the Meatloaf Mixture
- In a large mixing bowl, combine 1 1/2 pounds ground beef, 1 cup breadcrumbs, 1/2 cup milk, 2 minced garlic cloves, 1 beaten egg, 2 tablespoons Worcestershire sauce, 1 tablespoon Dijon mustard, 1 teaspoon dried thyme, 1/2 teaspoon salt, and 1/2 teaspoon black pepper.
- Mix gently with your hands or a spatula until just combined—overmixing can result in a dense loaf.
- Fold in the cooled caramelized onions and half of the shredded Gruyère cheese. This ensures cheesy, oniony goodness in every bite.
3. Shape and Bake
- Preheat your oven to 350°F (175°C).
- Shape the meat mixture into a loaf (about 8×4 inches) and place it in a lightly greased baking dish or loaf pan.
- Bake for 1 hour or until the internal temperature reaches 160°F (70°C).
Tip: Place a piece of parchment paper underneath for easier cleanup.
4. Add the Cheesy Topping
- Remove the meatloaf from the oven. Sprinkle the remaining Gruyère cheese evenly over the top.
- Return to the oven and bake for an additional 5–10 minutes, or until the cheese is melted, bubbly, and slightly golden.
5. Rest and Serve
- Let the meatloaf rest for 10 minutes before slicing. This helps the juices redistribute and keeps each slice perfectly moist.
- Slice, serve, and enjoy with your favorite sides—think mashed potatoes, roasted vegetables, or a crisp green salad.
Expert Tips & Variations
- Make Ahead: Caramelize the onions in advance and refrigerate. You can also assemble the meatloaf up to a day ahead and bake when ready.
- Cheese Options: If Gruyère isn’t available, Swiss, provolone, or even mozzarella work well.
- Meat Mixture: For extra juiciness, swap out 1/2 pound of beef for ground pork or turkey.
- Low-Carb Adaptation: Replace breadcrumbs with crushed pork rinds or almond flour.
- Onion Add-Ins: A splash of sherry or white wine with the onions adds classic French flavor.
- French Onion Gravy: For extra indulgence, serve with a quick pan gravy made by simmering beef broth with a bit of caramelized onion and thickening with cornstarch.
Storage & Serving Suggestions
Storing: Leftover meatloaf keeps beautifully! Wrap slices tightly and refrigerate for up to 4 days. To freeze, wrap individual portions and store in an airtight container for up to 2 months.
Serving Ideas:
- Pair with buttery mashed potatoes or creamy polenta for ultimate comfort.
- Serve leftovers on toasted sourdough with a smear of Dijon for a gourmet sandwich.
- Add a fresh green salad for a balanced meal.
