In a large skillet, heat the olive oil over medium-high heat. Add the beef stew meat and sear on all sides until browned, about 5-7 minutes. Transfer the browned beef to the crock pot.
In the same skillet, add diced onion and minced garlic. Sauté for 2-3 minutes until onions are translucent.
In a bowl, mix together beef broth, mushroom soup, Worcestershire sauce, dried thyme, paprika, salt, and pepper. Pour this mixture over the seared beef in the crock pot.
Cover the crock pot and cook on low for 6-8 hours or on high for 3-4 hours until the beef is tender.
In the last 30 minutes of cooking, mix the cornstarch with water to create a slurry. Stir it into the gravy mixture in the crock pot to thicken the sauce.
Once the beef is tender and the gravy has thickened, taste and adjust seasonings if necessary. Stir gently to coat the beef in the gravy.
Notes
Serve the beef tips and gravy over mashed potatoes or rice for a hearty meal. Garnish with fresh parsley to add a pop of color.
