Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 1 hour
• Total Time: 1 hour 30 minutes
• Servings: 6
• Yield: 1 casserole
• Dietary Type: Dairy-containing

Ingredients

• 4 cube steaks
• 4 tablespoons bacon drippings
• 2 (4 ounce) cans mushrooms
• 2 onions, thinly sliced
• 1 (10 1/2 ounce) can condensed cream of mushroom soup
• 2/3 cup buttermilk
• 2 tablespoons finely snipped parsley
• 1 teaspoon salt
• 1/4 teaspoon pepper
• 1/4 teaspoon dry mustard
• 4 medium potatoes, thinly sliced

Equipment Needed

• Large Skillet
• Paper Towels
• 2 1/2-Quart Casserole Dish
• Mixing Bowl

Instructions

1. Begin by heating the bacon drippings in a large skillet over medium-high heat. The bacon drippings lend a wonderful smoky depth to the steak, but you can substitute with vegetable oil if desired.

2. Brown the cube steaks in the hot drippings. Work in batches if necessary to avoid overcrowding the pan, which can lower the heat and result in steaming rather than browning. Browning the steak is crucial for developing flavor, so take your time and achieve a nice sear on all sides.

3. Remove the browned steaks from the skillet and set aside. Don’t worry about cooking them all the way through at this point, as they will continue to cook in the casserole.

4. In the same skillet, add the thinly sliced onions and mushrooms. Sauté them until they are tender and slightly caramelized. This process will release their natural sweetness and create a flavorful base for the casserole. Be patient and allow the onions to soften and turn translucent before adding the mushrooms.

5. Drain the steaks, mushrooms, and onion slices on paper towels to remove excess grease. This will help prevent the casserole from becoming too heavy and greasy.

6. In a mixing bowl, combine the condensed cream of mushroom soup, buttermilk, finely snipped parsley, salt, pepper, and dry mustard. Blend all the ingredients together until smooth and well combined. The buttermilk adds a tangy richness to the sauce, while the dry mustard provides a subtle hint of spice. Fresh parsley brightens the flavor of the soup.

7. Grease a 2 1/2-quart casserole dish.

8. Now it’s time to assemble the casserole. Place alternate layers of the thinly sliced potatoes, onion and mushroom slices, steak, and sauce in the prepared casserole dish. Start with a layer of potatoes on the bottom, followed by a layer of the onion and mushroom mixture, then a layer of steak, and finally a generous drizzle of the sauce. Repeat these layers until all the ingredients are used, ending with a layer of sauce on top. This layering technique ensures that each bite of the casserole is packed with flavor and texture.

9. Bake the casserole uncovered in a preheated 350°F (175°C) oven for 1 hour, or until the potatoes are tender. To check for doneness, insert a fork or knife into the center of the potato layer. If it slides in easily, the potatoes are cooked through. If the top of the casserole starts to brown too quickly, you can loosely cover it with aluminum foil for the last 15-20 minutes of baking.

Expert Tips & Tricks

• For a richer flavor, use beef broth instead of buttermilk in the sauce.
• If you don’t have bacon drippings on hand, substitute with olive oil or butter.
• To save time, use pre-sliced mushrooms and onions.
• Add a layer of shredded cheese (cheddar, mozzarella, or Gruyere) during the last 15 minutes of baking for a cheesy topping.
• If you’re short on time, you can partially cook the potatoes in the microwave before layering them in the casserole.
• For a spicier kick, add a pinch of red pepper flakes to the sauce.
• If the sauce becomes too thick during baking, add a splash of milk or broth to thin it out.

Serving & Storage Suggestions

Serve the steak and mushroom casserole hot, straight from the oven. Garnish with extra fresh parsley for a pop of color and freshness. This casserole pairs well with a simple side salad, steamed green beans, or crusty bread for soaking up the delicious sauce.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply microwave individual portions or bake the entire casserole in a preheated oven at 350°F (175°C) until heated through. For longer storage, the casserole can be frozen for up to 2-3 months. Thaw completely in the refrigerator before reheating.
