Al's baked Swiss steak is a variation on another excellent recipe. But I couldn't make Swiss steak without green bell peppers or garlic, and I season the meat instead of the flour, which makes it more intensely flavored.
Pounding the beef to ¼-inch thickness is crucial for tenderness, especially with a cut like round steak. Ensure a deep, even sear on the beef before braising; this builds a foundational layer of flavor through the Maillard reaction. Don't rush the braising time; the 1.5 hours ensures the beef breaks down beautifully into fork-tender perfection. Consider deglazing the skillet with a splash of red wine or a touch of tomato paste browned with the aromatics before adding the other sauce ingredients for added depth. Fresh herbs like thyme or bay leaf can also enhance the aromatics during the braising. The final sprinkle of sharp cheddar provides a pleasant tang and melty finish, contrasting nicely with the savory stewed vegetables.
