1-First, gather your ingredients and slice the yellow onion thinly this helps it caramelize beautifully in the butter.

2-Heat a pan to slowly cook the onion until it’s golden, which adds that sweet depth we all love.

3-Once done, mix the 2 pounds of lean ground beef with the caramelized onion, 3/4 cup Italian bread crumbs, 2 large eggs, 3/4 cup milk, 1 tablespoon Worcestershire sauce, and the beefy onion soup mix in a big bowl.

4-Next, shape the mixture into a loaf and place it in your crockpot, making sure it’s even for consistent cooking.

5-Pour in the 10.5 ounce can of French onion soup around the edges to keep everything moist.

6-Cover and cook on low for 6-7 hours, or on high for 3-4 hours, depending on your day.

7-If you’re adapting for dietary needs, add your swaps at the mixing stage, like using plant-based options for a vegan twist.

8-After cooking, let the beefloaf rest for about 10 minutes before slicing, then top with the 8 slices of Swiss cheese for that melty goodness.

9-Garnish with chopped parsley if you like, and serve it up hot.
