🛒 Ingredients
For the meatloaf
-
2 lbs ground beef (80/20 works best for moisture)
-
1 packet French onion soup mix
-
1 cup breadcrumbs (plain or Italian)
-
2 large eggs
-
½ cup milk
-
1 cup shredded Swiss cheese (or Gruyère if you’re fancy)
-
1 medium onion, thinly sliced
-
2 tbsp butter
-
1 tbsp olive oil
-
1 tsp Worcestershire sauce
-
½ tsp garlic powder
-
½ tsp black pepper
Optional but recommended topping
-
1 cup shredded Swiss or mozzarella cheese (for the end)
🔪 Step-by-Step Directions
Step 1: Caramelize the onions
-
Heat a skillet over medium heat.
-
Add butter and olive oil.
-
Add sliced onions and cook for 12–15 minutes, stirring often.
-
Cook until soft, golden, and sweet (don’t rush this—this is the flavor).
-
Remove from heat and let cool slightly.
Step 2: Make the meatloaf mixture
-
In a large bowl, add:
-
Ground beef
-
French onion soup mix
-
Breadcrumbs
-
Eggs
-
Milk
-
Worcestershire sauce
-
Garlic powder
-
Black pepper
-
-
Add ¾ of the caramelized onions to the bowl.
-
Gently mix with your hands until just combined.
👉 Don’t overmix or the meatloaf will be dense.
Step 3: Add cheese
-
Fold in 1 cup shredded Swiss cheese.
-
Shape the mixture into a loaf (oval shape works best).
Step 4: Prepare the crockpot
-
Spray the crockpot with nonstick spray or line with parchment.
-
Place remaining caramelized onions on the bottom.
-
Set the meatloaf on top of the onions.
(This keeps it from sitting in grease and adds flavor.)
Step 5: Slow cook
-
Cover and cook:
-
LOW: 5–6 hours
-
HIGH: 3–4 hours
-
-
Meatloaf is done when internal temp reaches 160°F (71°C).
Step 6: Cheesy finish (optional but amazing)
-
About 15 minutes before serving, sprinkle cheese on top.
-
Cover and let it melt.
Step 7: Rest & serve
-
Let meatloaf rest 10 minutes before slicing.
-
Serve with mashed potatoes, green beans, or buttered noodles.
