01 - In a shallow dish, combine the flour, salt, black pepper, and paprika. Dredge each cube steak in the seasoned flour mixture, shaking off any excess. Reserve 2 tablespoons of the seasoned flour for the gravy.
02 - Heat the vegetable oil and 1 tablespoon of butter in a large skillet over medium-high heat. Brown the coated cube steaks for 2 to 3 minutes per side until a golden crust forms. Transfer the steaks to a plate and set aside.
03 - Reduce the heat to medium. Add the remaining tablespoon of butter to the skillet along with the sliced onions and mushrooms. Cook, stirring occasionally, until the onions are softened and the mushrooms are nicely browned, about 6 to 8 minutes.
04 - Add the minced garlic and the reserved seasoned flour to the skillet. Stir well and cook for 1 minute to toast the flour and bloom the garlic.
05 - Slowly pour in the beef broth and Worcestershire sauce, stirring constantly and scraping up any browned bits from the bottom of the skillet. Stir in the milk and bring the mixture to a gentle simmer.
06 - Return the browned cube steaks to the skillet, nestling them down into the gravy. Cover with a lid and simmer on low heat for 20 minutes, or until the steaks are fork-tender and the gravy has thickened to your liking.
07 - Taste the gravy and adjust the seasoning with salt and pepper if needed. Garnish with chopped fresh parsley before serving. Pair with mashed potatoes, rice, or egg noodles to soak up the rich gravy.
