Follow these steps to create mouthwatering Steak Bites in Gravy:

1. Prepare Ingredients: Cut the beef sirloin into bite-sized pieces, chop the onion, and mince the garlic.
2. Sear the Steak: In a large skillet, heat olive oil over medium-high heat. Once hot, add the beef pieces in a single layer. Sear for about 2-3 minutes per side until browned. Remove from the skillet and set aside.
3. Sauté Onions and Garlic: In the same skillet, add butter. Once melted, add the chopped onion. Sauté until the onion is translucent, about 4-5 minutes. Then add the minced garlic and cook for another minute until aromatic.
4. Combine Ingredients: Return the seared steak to the skillet. Pour in the beef broth, soy sauce, and Worcestershire sauce. Stir well to combine.
5. Add Seasonings: Sprinkle dried thyme, smoked paprika, salt, and pepper into the skillet. Stir to incorporate.
6. Simmer: Bring the mixture to a gentle boil, then reduce the heat. Allow it to simmer for 20-25 minutes, stirring occasionally.
7. Thicken Gravy (Optional): To thicken the gravy, mix cornstarch with an equal amount of cold water to create a slurry. Stir into the gravy and let cook for an additional 5 minutes until thickened.
8. Taste and Adjust: Sample the gravy and adjust seasoning with more salt or pepper as necessary.
9. Serve Immediately: Once thickened to your liking, remove from heat and get ready to serve!

These steps will lead you to an incredible meal that is not only easy to prepare but also bursting with flavors.
