Crockpot French Onion Meatloaf Ingredients
• Note: Gather these ingredients to create a mouthwatering Crockpot French Onion Meatloaf with Melted Swiss Cheese.
For the Meatloaf
- Ground Beef (80/20) – This is the main protein source that provides rich flavor and moisture; substitute with ground turkey for a leaner option.
- Sweet Onions – Adds depth and sweetness through caramelization; use yellow onions if sweet onions are unavailable.
- Salted Butter – Used for caramelizing onions, contributing richness; swap it with unsalted butter for a low-sodium option.
- Olive Oil – Helps to sauté the onions without burning; you can substitute with vegetable oil if preferred.
- Sea Salt & Coarse Black Pepper – Essential for enhancing flavor; adjust according to your taste preference.
- Granulated Sugar – Aids in caramelization and balances flavors; omit if adhering to a sugar-restricted diet.
- Cooking Sherry (optional) – Adds an extra layer of flavor; use vegetable broth as a substitute for a non-alcoholic version.
- Italian-style Breadcrumbs – Acts as a bonding agent, providing texture; gluten-free breadcrumbs can be used as an alternative.
- Whole Milk – Adds moisture and richness; consider dairy-free milk for a lactose-free alternative.
- Large Egg – Serves as a binder to hold the meatloaf together; can be replaced with a flax egg for a vegan option.
- French Onion Soup Mix – Infuses the classic flavor into the meatloaf; you can make a homemade mix with onion powder and extra spices if desired.
- Worcestershire Sauce – Provides a rich, umami depth; swap with soy sauce for a gluten-free option.
For the Topping
- Swiss Cheese (or Gruyère/Provolone) – Melts beautifully and adds creamy texture on top; experiment with sharp cheddar for a different flavor profile.
- Fresh Thyme Sprigs – Optional garnish that elevates both presentation and flavor.
Step‑by‑Step Instructions for Crockpot French Onion Meatloaf With Melted Swiss Cheese
Step 1: Prepare Onions
In a skillet, melt 2 tablespoons of salted butter and 1 tablespoon of olive oil over medium heat. Add thinly sliced sweet onions, along with a pinch of sea salt, coarse black pepper, and 1 teaspoon of granulated sugar. Stir occasionally for about 15-20 minutes until the onions are deep golden brown and caramelized. Set the sautéed onions aside to cool slightly while you mix the meatloaf ingredients.
Step 2: Mix Meatloaf Ingredients
In a large mixing bowl, combine 1 pound of ground beef, 1 cup of Italian-style breadcrumbs, 1/2 cup of whole milk, and 1 large egg. Then, stir in the packet of French onion soup mix, 2 tablespoons of Worcestershire sauce, and half of the cooled caramelized onions. Mix gently with your hands until just combined, being careful not to overmix for a tender meatloaf.
Step 3: Shape and Cook
Transfer the meat mixture into the Crockpot, shaping it into a loaf. Smooth the surface with a spatula for even cooking. Top the meatloaf with the remaining caramelized onions, spreading them evenly. Cover the Crockpot with the lid, ensuring it fits snugly to lock in moisture and flavors.
Step 4: Slow Cook
Set your Crockpot to low and allow the meatloaf to cook for 6-8 hours, or until the internal temperature reaches 160°F (70°C). You’ll know the meatloaf is ready when it’s firm to the touch and the juices run clear. This hands-off process infuses the meatloaf with delicious flavors from the onions and spices.
Step 5: Add Cheese
About 15 minutes before the cooking time is up, carefully lift the lid and place slices of Swiss cheese on top of the meatloaf. Pour a little of the melted butter from the skillet over the cheese for added richness. Re-cover the Crockpot and let the cheese melt into gooey perfection while the meatloaf finishes cooking.
Step 6: Serve
Once the meatloaf is perfectly cooked, carefully remove it from the Crockpot. Let it rest for a few minutes before slicing. Garnish each slice with fresh thyme sprigs for a pop of color and flavor, and serve your Crockpot French Onion Meatloaf with Melted Swiss Cheese alongside your favorite sides for a cozy meal.
