Preparing French Onion Meatloaf
Preheat and Prepare Your Tools
Before diving into the delicious world of French Onion Meatloaf, it's crucial to set the stage for a smooth cooking experience. First, arrange a rack in the middle of your oven and preheat it to 350°F. While the oven warms up, gather your tools: you'll need a 9x5-inch loaf pan, aluminum foil, a large heavy-bottomed pot or Dutch oven, and a mixing bowl. Having everything at your fingertips not only makes the process easier but also more enjoyable – trust me, you'll want to keep your kitchen clutter-free when you’re in a rhythm!
Caramelizing the Onions to Perfection
The star of your French Onion Meatloaf is undoubtedly the caramelized onions. In your pot or Dutch oven, heat up 2 tablespoons of olive oil over medium-high heat until it shimmers. Toss in 2 pounds of thinly sliced yellow onions and a pinch of baking soda to speed up the caramelization process. Stir every few minutes, enjoying the sweet aroma filling your kitchen. After about 15 minutes of cooking, you’ll notice a beautiful golden hue. Keep stirring more frequently until those onions reach a rich, deep golden-brown—this should take another 10-15 minutes. Not only will the flavors intensify, but you’ll also be tempted to sneak a taste (and you should!).
Mixing the Meatloaf Ingredients
Now that your onions are perfectly caramelized, it's time to combine them with the meatloaf ingredients. In a large bowl, mix ½ cup of unseasoned dried breadcrumbs with ½ cup of whole or 2% milk, letting the breadcrumbs soak for a minute. Then, stir in those sweet onions (save a little for garnish if you like), along with minced garlic, Worcestershire sauce, kosher salt, and freshly ground black pepper.
This tip is a game-changer: make sure to use high-quality ingredients for a flavor boost! Once everything is well mixed, it’s time to incorporate the meat and eggs—choose a blend of ground beef, veal, or pork for a balance of flavor and moisture.
Shaping the Meatloaf
Gently mix the meat with your hands, being careful not to overwork it—that can lead to a dense texture. Once combined, transfer the mixture into your prepared loaf pan, pressing it down to form an even layer. This shape helps it cook uniformly and makes it visually appealing when served.
Baking and Broiling to Finish
Pop your meatloaf into the preheated oven and let it bake for 55 to 60 minutes. You’ll want to check that the middle reaches a safe temperature of at least 165°F using an instant-read thermometer.
Once baked, it’s time for a delicious finishing touch! Switch your oven to broil, and sprinkle the reserved caramelized onions and 1 cup of shredded Gruyère cheese over the top. Broil until bubbly and browned (about 2 minutes). Remember to keep an eye on it so it doesn’t burn. Let it rest for 15 minutes before slicing, allowing the juices to redistribute.
