Ingredients for French Onion Meatloaf

• Yellow onions: These bring sweetness to the meatloaf. You can also use Vidalia or sweet onions for an even milder flavor.
• Butter & olive oil: A combination of butter and olive oil gives a rich base for caramelizing the onions and helps create a moist meatloaf.
• Thyme: Adds an earthy, herbal note. You can also use rosemary or Italian seasoning if preferred.
• Balsamic vinegar: A splash of balsamic adds depth and a touch of acidity to balance the sweetness of the onions.
• Ground beef: Provides the savory base for the meatloaf. For a juicy loaf, choose 80/20 ground beef.
• Ground pork: Adds moisture and richness to the meatloaf.
• Eggs: Help bind the meatloaf together.
• Breadcrumbs: Whole-grain breadcrumbs or panko provide texture. For a gluten-free version, use oat flour or almond flour.
• Milk: Whole milk adds creaminess, but you can use a dairy-free option like almond milk if needed.
• Dijon mustard: Brings a subtle tang and depth of flavor.
• Worcestershire sauce: Adds a savory, umami flavor.
• Seasonings: Garlic powder, onion powder, smoked paprika, salt, and pepper enhance the flavor profile.
• Gruyère cheese: Melts beautifully on top and gives a nutty, cheesy finish to the meatloaf.

Alternative Ingredient Suggestions

• Ground turkey or chicken: If you’re looking for a leaner version of French Onion Meatloaf, swap the ground beef and pork for turkey or chicken. Just be mindful to avoid overcooking, as lean meats can dry out faster.
• Gluten-free breadcrumbs: If you need a gluten-free option, substitute regular breadcrumbs with oat flour, ground oats, or almond flour.
• Cheese options: Gruyère adds a rich flavor, but you can use Swiss cheese, mozzarella, or provolone for similar melty goodness.

Step-by-Step Instructions for French Onion Meatloaf

1. Caramelize the onions: In a skillet, melt butter and olive oil over medium-low heat. Add the onions and sprinkle with salt. Cook, stirring occasionally, for 25-30 minutes until they’re deeply golden and jammy. Add thyme and balsamic vinegar (if using), then set aside half of the caramelized onions for the topping.
2. Prepare the panade: In a large mixing bowl, whisk together eggs, milk, Dijon mustard, Worcestershire sauce, garlic powder, onion powder, smoked paprika, salt, and pepper. Stir in the breadcrumbs and let them soak for about 5 minutes.
3. Mix the meatloaf ingredients: Add the ground beef, ground pork, most of the caramelized onions, and Gruyère cheese to the soaked breadcrumbs. Gently mix everything together until just combined. Be careful not to overmix, as this could result in a tough meatloaf.
4. Shape and bake: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly oil a loaf pan. Shape the meat mixture into a loaf and place it on the sheet (or in the pan). Bake for 40 minutes.
5. Make it cheesy: Remove the meatloaf from the oven and top with the reserved caramelized onions and Gruyère cheese. Return it to the oven for another 15-20 minutes, or until the cheese is melted and bubbly, and the internal temperature reaches 160°F.
6. Rest and slice: Let the meatloaf rest for 10 minutes before slicing. Garnish with fresh parsley for an added touch of color.

Tips & Tricks for the Best French Onion Meatloaf

• Don’t rush the onions: Caramelizing the onions slowly over low heat is key to developing their sweet, savory flavor. This step may take some time, but it’s worth it for the depth of flavor it adds.
• Soak the breadcrumbs: For the juiciest meatloaf, let the breadcrumbs soak in the milk and egg mixture before combining with the meat. This helps create a tender texture.
• Avoid overmixing: Mix the meatloaf ingredients gently. Overmixing can cause the loaf to be dense and tough.
• Check the internal temperature: Ensure the meatloaf is cooked through by checking the internal temperature with a meat thermometer. It should reach 160°F (71°C) for a perfectly cooked meatloaf.

Pairing Ideas and Variations for French Onion Meatloaf

This French Onion Meatloaf pairs wonderfully with a variety of side dishes, including:

• Mashed potatoes: Creamy mashed potatoes are the ultimate side for this meatloaf.

• Buttered egg noodles: Another cozy side that brings comfort to the meal.
