Sirloin and Tenderloin Roasts are pricier but more tender, which requires less cooking time to render down than tougher cuts of meat. (Ideal for stove top cooking.)
Chuck Roast, Rump Roast, and Bottom Rounds are more economical cuts that render down nicely if cooked using the slow cooker method. The best option is Chuck, then Rump, then Bottom Round.
You may also have the option to buy packaged stew meat that’s already cubed. While this also will work, I prefer to purchase it whole so that I can choose the cut I want. Stew meat isn’t always clearly labeled as to what cut it’s from. (But it’s almost always a tougher cut that requires slow cooking.)

PRO TIPS
Wine: Cabernet Sauvignon, Merlot, and Pinot Noir are the best wines to use for deglazing the skillet in this recipe. An equal amount of beef broth + 2 tbsp red wine vinegar can be used if you don’t cook with wine.
Broth: A little chicken broth is used in this recipe along with the beef broth as the contrast adds a nice depth of flavor. All beef broth may be used if preferred.
Mushrooms: I use white button mushrooms that are already sliced/washed as it’s a nice time saver. Cooking the mushrooms first and adding them to the soup at the end is the best way to preserve their color, flavor, and texture. If they’re cooked in the soup, they can become waterlogged and rubbery. This ingredient can be skipped for non-mushroom lovers, there are still plenty of other vegetables to make this complete.
Tenderizing the Meat: If you purchased your meat whole (as opposed to cubed stew meat), I recommend covering it with plastic wrap and tenderizing each side with a meat mallet for extra tender results!
Cooking the Meat: The beef is seasoned and sauteed to create a textured outer crust. This also adds “fond” (flavor) to the pan, which is deglazed with wine to make the soup more flavorful. The beef is then cooked low and slow which ensures it’s nice and tender.
