How to make Crockpot French Onion Meatloaf better?
Opt for lean ground beef or turkey to avoid any greasiness. Be careful not to overmix, as the meatloaf will become dense. A delicate blend provides the pastry with a yielding bite.
Place parchment paper down in the base of the crockpot for easier lifting. It helps the loaf maintain its shape and cuts down on cleanup round 2. Allow the meatloaf to rest for at least 10 minutes before slicing (its internal temp will rise to 155 degrees F while it rests). That helps the juices calm down.
Check for doneness with a meat thermometer. The middle should be at 160°F. If you are using cheese add it during the final 30 minutes so that it melts just right.
Think about sauces or glazes as an additional layer. A paste of ketchup and Worcestershire can make a great crust. Season liberally with herbs and spices to keep it from being bland.
If it’s texture ya crave, think about mixing in finely chopped onions or bell peppers. These add flavor and help keep things moist. For a smoky bent, you can use smoked paprika or liquid smoke.
Cook on low for best results. High heat may dry the loaf. With these easy tricks, your crockpot French onion meatloaf will be perfect.
Variations to Try
Crockpot French Onion Meatloaf is so delicious and such an appetizing meal and so easy to put together to your taste or preference for diet. Here are a few tasty interpretations to try:
Cheesy French Onion Meatloaf:
Toss shredded Gruyère or Swiss cheese in the meat and place a layer more for good measure over the top for the last 30 minutes of slow cooking. The cheese melts into the meatloaf, yielding a gooey, satisfying bite.
Mushroom French Onion Meatloaf:
Sautéed mushrooms contribute earthy flavor and moisture. Stir chopped mushrooms directly into the meatloaf mixture or pile them on top to add umami depth.
Bacon Wrapped:
Roll the meat in bacon and put it in the crock pot. The bacon crisps as it contributes its smoky flavor, and it secures about half the moisture.
Low-Carb/Keto Version:
Substitute crushed pork rinds or almond flour for bread crumbs. And the sugar-free French onion soup mix ensures they don’t take a dive off of your keto friendly wagon.
Turkey or Chicken French Onion Meatloaf:
To make a leaner option, replace the ground beef with turkey or chicken. Just toss in some extra seasoning and moisture, such as a drizzle of olive oil or an egg yolk, to stave off dryness.
Gluten-Free Option:
Substitute gluten free breadcrumbs or oats and be sure your French onion soup mix is certified gluten free.
Mini Meatloaf Muffins:
Shape mixture into mini meatloaf “muffins” (I used a decorative muffin tin that is a crock pot safe). These are great for portion control and faster cooking.
Spicy French Onion Meatloaf:
Add some diced jalapeños, chili flakes or pepper jack cheese for a spicy twist that contrasts nicely with the sweet-savory onion taste.
Thanks to these tweaks your crockpot French onion meatloaf will remain fresh, fun, and just right for your family!
