Whether you’re looking to enhance the texture, add a cheesy surprise, or make it healthier, there’s a version for every taste and preference.

French Onion Meatloaf with Mushrooms

If you’re a fan of earthy flavors, adding mushrooms to your French onion meatloaf is a game-changer. Finely chopped mushrooms blend seamlessly into the meat mixture, adding moisture and a deep umami flavor that complements the caramelized onions perfectly.

How to Do It:

• Chop 1 cup of cremini or button mushrooms finely and sauté them in butter until tender before mixing them into the meat.

Cheesy Stuffed French Onion Meatloaf

Love cheese? This variation takes things to the next level by adding layers of gooey, melted cheese inside the meatloaf. When you cut into it, the cheese oozes out, making every bite an indulgent delight.

Pairing this version with mashed potatoes makes for an ultra-comforting meal that’s sure to satisfy any cheese lover.
