Step‑by‑Step Instructions for Crockpot French Onion Meatloaf
Step 1: Prepare Onion Base
In a skillet, melt 2 tablespoons of butter over medium heat. Add thickly sliced onions and cook for about 15-20 minutes, stirring occasionally, until they turn golden brown and caramelized. Once done, set the onions aside to build layers of flavor in your Crockpot French Onion Meatloaf.
Step 2: Mix Meatloaf Ingredients
In a large mixing bowl, combine 2 pounds of ground beef, one packet of dry onion soup mix, minced garlic (optional), and 1 cup of breadcrumbs. Crack in 2 eggs, pour in ½ cup of milk, ¼ cup of ketchup, and a dash of Worcestershire sauce, along with thyme, salt, and pepper to taste. Mix gently until just combined, ensuring not to overwork the meat.
Step 3: Shape Meatloaf
Transfer the meat mixture to a clean surface and shape it into a loaf, approximately 8-10 inches long. Carefully place the meatloaf into the prepared Crockpot, making sure it’s centered to allow even cooking. This Crockpot French Onion Meatloaf will become incredibly juicy as it cooks slowly.
Step 4: Add Onions & Broth
Layer the caramelized onions evenly over the top of the shaped meatloaf. Gradually pour 1 cup of beef broth into the Crockpot around the meatloaf—taking care to avoid pouring directly over the top. This will keep the meatloaf moist while allowing rich flavors to develop during cooking.
Step 5: Cook
Cover the Crockpot and set it to LOW for 6-7 hours or HIGH for 3-4 hours, until the internal temperature of the meatloaf reaches 160°F. The aroma will fill your kitchen, signaling the comforting transformation of your Crockpot French Onion Meatloaf.
Step 6: Add Optional Cheese
In the last 10 minutes of cooking, sprinkle 1 cup of shredded Gruyère or Swiss cheese on top of the meatloaf. Re-cover and let the heat melt the cheese into a delicious gooey layer, enhancing the comfort food experience you crave.
Step 7: Serve
Once cooked, carefully remove the meatloaf from the Crockpot and let it rest for 10 minutes before slicing. This resting period helps it firm up for easy cutting. Serve your Crockpot French Onion Meatloaf warm, spooning the flavorful broth and onions over each slice for a delightful meal.
