Ingredients:
2 pounds beef stew meat, cut into bite-size pieces
3 (10.5-ounce) cans condensed French onion soup
1 (32-ounce) carton beef broth (low-sodium preferred)
1 (1-ounce) packet onion soup mix
2 tablespoons butter (or olive oil)
Directions:
Add the beef stew meat to the bottom of a 5–6 quart slow cooker.
Sprinkle the onion soup mix evenly over the meat.
Pour in the condensed French onion soup and beef broth. Gently stir so the meat is mostly submerged.
Dot the top with butter (or drizzle with olive oil) to add richness.
Cover and cook on LOW for 7–8 hours or HIGH for 4–5 hours, until the beef is fork-tender and the broth is deeply flavorful.
Taste and season with salt and pepper if needed. Serve hot.

Top with shredded cheese and toasted baguette or Texas toast

Spoon over mashed potatoes or buttered egg noodles for an extra-hearty meal
