Ingredients You’ll Need
Here’s everything you need to create your own French Onion Meatloaf:
- 1 1/2 pounds ground beef
- 1 cup breadcrumbs
- 1/2 cup milk
- 2 large onions, thinly sliced
- 2 cloves garlic, minced
- 1 egg, beaten
- 2 tablespoons Worcestershire sauce
- 1 tablespoon Dijon mustard
- 1 teaspoon dried thyme
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 2 tablespoons butter
- 1/4 cup beef broth
- 1 cup shredded Gruyère or Swiss cheese
- Optional: 1 teaspoon vanilla extract (for a subtle, sweet undertone)
Kitchen Equipment Needed
Before you start, make sure you have the following tools:
- Large skillet (preferably non-stick or stainless steel for caramelizing onions)
- Mixing bowls
- Loaf pan (9×5 inch)
- Measuring cups and spoons
- Wooden spoon or spatula
- Sharp knife
- Meat thermometer (optional but recommended)
- Aluminum foil or parchment paper
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a loaf pan or line it with parchment paper for easy cleanup.
Step 2: Caramelize the Onions
Melt butter in a skillet over medium heat. Add the thinly sliced onions and cook slowly, stirring occasionally, for 20–25 minutes until golden and deeply caramelized. Add minced garlic and sauté for another 1–2 minutes.
Pro Tip: A splash of balsamic vinegar or a pinch of sugar can help accelerate and deepen the caramelization.
Remove half the onions from the skillet and set them aside to cool.
Step 3: Mix the Meatloaf
In a large bowl, combine ground beef, breadcrumbs, milk, egg, Worcestershire sauce, Dijon mustard, thyme, salt, pepper, and the cooled caramelized onions. Mix until just combined—do not overwork the meat or the loaf will be dense.
Step 4: Shape and Bake
Transfer the meat mixture into your prepared loaf pan. Pour the beef broth over the top to help retain moisture while baking.
Bake uncovered for 45 minutes.
Step 5: Add Cheese and Toppings
Remove the loaf from the oven. Top it with shredded Gruyère cheese and the remaining caramelized onions. Return to the oven for another 15 minutes until the cheese is melted and bubbly, and the internal temperature reaches 160°F (71°C).
Step 6: Rest and Serve
Allow the meatloaf to rest for 10 minutes before slicing. This helps the juices redistribute and keeps the meat tender. Serve hot with your favorite sides.
Tips, Swaps, and Variations
- Cheese Alternatives: Swap Gruyère with Swiss, provolone, or mozzarella if preferred.
- Make it Lighter: Use ground turkey or chicken for a leaner version. Add a splash of olive oil to compensate for the lower fat content.
- Gluten-Free Option: Use gluten-free breadcrumbs and double-check that your Worcestershire sauce is certified gluten-free.
- Add Veggies: Sneak in grated carrots, zucchini, or mushrooms to boost the nutrition profile.
- Make it Ahead: Assemble the meatloaf and refrigerate up to 24 hours before baking. Add 5-10 minutes to the baking time if starting cold.
How to Store and Reheat Leftovers
Storage:
Store leftover meatloaf in an airtight container in the refrigerator for up to 4 days.
Freezing:
Wrap individual slices in foil and freeze for up to 2 months. Reheat from frozen in the oven at 325°F (163°C) for 20–25 minutes.
Reheating:
Microwave on medium heat in 30-second intervals or warm in a covered dish in the oven at 300°F (150°C) for about 15 minutes.
Food and Drink Pairings
- Side Dishes: Try creamy mashed potatoes, roasted green beans, buttered egg noodles, or a crisp arugula salad with lemon vinaigrette.
- Drinks: A bold red wine like Cabernet Sauvignon or a dry white like Chardonnay complements the savory richness. For non-alcoholic options, a sparkling apple cider or a strong iced tea is excellent.
FAQs
Can I use onions that are already caramelized?
Yes! If you have pre-caramelized onions from another recipe, go ahead and use them to save time.
Is vanilla extract necessary?
Not at all. It’s optional and unconventional for meatloaf but can add an interesting sweetness. If you’re feeling adventurous, try it once!
How do I know the meatloaf is done?
Use a meat thermometer to ensure the internal temperature is at least 160°F (71°C). The juices should run clear, and the loaf should feel firm to the touch.
Can I make this in a muffin tin for mini meatloaves?
Absolutely. Divide the mixture into greased muffin tins and reduce baking time to about 20–25 minutes. Add cheese and onions during the last 5 minutes.
