Ingredients
  

  • 1 ½ lbs beef stew meat cut into cubes
  • 1 tablespoon olive oil
  • 1 medium onion chopped
  • 3 cloves garlic minced
  • 3 large carrots peeled and sliced
  • 2 medium potatoes peeled and diced
  • 1 cup green beans trimmed and chopped
  • 1 cup corn kernels fresh or frozen
  • 1 can 14.5 oz diced tomatoes, undrained
  • ½ cup beef broth
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • ½ teaspoon paprika
  • Salt and pepper to taste

Instructions
 

  • Brown the beef: Heat olive oil in a large skillet over medium heat. Brown the beef stew meat in batches, about 3–4 minutes per batch. Transfer browned beef to the slow cooker.
  • Sauté the vegetables: In the same skillet, sauté the chopped onion and minced garlic for about 2 minutes until softened and fragrant.
  • Combine ingredients: Add the onion and garlic to the slow cooker along with the carrots, potatoes, green beans, corn, diced tomatoes, beef broth, thyme, oregano, paprika, salt, and pepper.
  • Slow cook: Cover and cook on low for 6–8 hours, or until the beef is tender and the vegetables are fully cooked.
  • Serve: Once the casserole is cooked, stir well and adjust seasoning if needed. Serve hot and enjoy!

Notes

  • Feel free to swap in other vegetables based on what’s in season—zucchini, bell peppers, or peas would work great.
  • You can substitute chicken broth for beef broth for a lighter version of the dish.
  • If you like a thicker casserole, you can mix in a slurry of cornstarch and water during the last 30 minutes of cooking.
