How to Make Slow Cooker 4-Ingredient French Onion Corned Beef
Ingredients:
- 2 pounds sliced deli corned beef
- 1 can (10.5 ounces) condensed French onion soup
- 1 cup low-sodium beef broth
- 2 tablespoons Dijon mustard
Directions:
Lightly coat the slow cooker insert with nonstick spray if desired. Add the sliced deli corned beef, separating some slices so the soup can settle between them.
In a small bowl, whisk together the condensed French onion soup, beef broth, and Dijon mustard until smooth.
Pour the soup mixture evenly over the corned beef, ensuring the slices are well coated.
Cover and cook on low for 2 to 3 hours, just until the meat is heated through and tender, and the flavors have blended. Stir once halfway through, if convenient, so the top slices stay moist.
Gently stir before serving, then spoon the corned beef and onion gravy over mashed potatoes, noodles, or rice.
