5-Ingredient Tax Season Oven Beef Strips
Prep Time: 5 minutes | Bake Time: 1 hour to 1 hour 20 minutes | Resting Time: 5 minutes | Total Time: Approximately 1 hour 10-30 minutes
Yield: 4 servings
Ingredients
-
1½ pounds beef strips (stir-fry beef or steak cut into thin strips)
-
1 (10.5-ounce) can condensed cream of mushroom soup
-
1 packet (about 1 ounce) dry onion soup mix
-
½ cup water
-
2 tablespoons soy sauce
Instructions
1. Preheat and Prepare:
Preheat your oven to 350°F (175°C). Set out a 9×13-inch glass casserole dish.
2. Add the Beef:
Place the raw beef strips directly into the glass casserole dish, spreading them out as evenly as possible so they are mostly in a single layer.
3. Make the Sauce:
In a medium bowl, stir together the condensed cream of mushroom soup, dry onion soup mix, water, and soy sauce until well combined. The mixture will look like a thick, pourable sauce.
4. Coat the Beef:
Pour the sauce mixture evenly over the raw beef strips, making sure most of the beef is coated. Use a spoon to gently nudge the sauce around so it seeps between the strips. Do not worry if a few pieces peek out.
5. Cover and Bake:
Cover the glass casserole dish tightly with aluminum foil. This helps the beef stay tender and keeps all the juices in the dish. Bake in the preheated oven for 1 hour.
6. Check for Tenderness:
After 1 hour, carefully remove the foil (watch out for steam). Give the beef and sauce a gentle stir and check for tenderness. If the beef strips are not as tender as you would like, re-cover and bake for an additional 15 to 20 minutes, until the beef is very tender and the sauce is bubbly and slightly thickened.
7. Rest and Serve:
Once done, let the dish rest for about 5 minutes so the juices settle. Taste the sauce and add a pinch of salt and pepper if needed. Serve the saucy beef strips over rice, mashed potatoes, or noodles.
Recipe Notes & Pro Tips
Choosing the Right Beef: Stir-fry beef, beef strips labeled “for stew” (cut smaller), or thinly sliced sirloin or flank steak all work well. The key is to cut the beef across the grain into thin strips, about ¼ inch thick and 2-3 inches long. Cutting across the grain shortens the muscle fibers, resulting in more tender meat.
Glass Dish Recommended: A glass casserole dish (like Pyrex) conducts heat evenly and allows you to see the bubbling sauce without lifting the foil. If using metal, reduce the oven temperature by 25°F and check for doneness a few minutes earlier.
Do Not Skip the Foil: The foil cover traps steam, which is essential for tenderizing the beef. Without it, the top of the beef can dry out while the bottom simmers. Keep the foil tightly sealed for the first hour of baking.
Soy Sauce and Salt: The dry onion soup mix and soy sauce both contain significant amounts of sodium. Taste the sauce before adding any extra salt. You will likely not need any.
Thicker Sauce: If you prefer a thicker, more gravy-like consistency, remove the beef from the dish after baking, then whisk 1 tablespoon of cornstarch mixed with 2 tablespoons of cold water into the remaining sauce. Return to the oven uncovered for 5-10 minutes, then pour back over the beef.
Add Vegetables: For a more complete one-dish meal, add 1 cup of sliced mushrooms, 1 cup of frozen peas, or 1 cup of thinly sliced bell peppers to the casserole dish before adding the sauce.
Serving Suggestions
These saucy beef strips are all about the gravy, so serve them over something that can soak it up:
-
White rice or brown rice
-
Mashed potatoes
-
Buttered egg noodles
-
Steamed rice noodles
-
Cauliflower rice (for a lower-carb option)
For a complete meal, add a simple green vegetable on the side:
-
Steamed broccoli or green beans
-
Roasted asparagus
-
A crisp garden salad
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. The beef will become even more tender as it sits, and the flavors will continue to meld.
To reheat, warm individual portions in the microwave in 60-second bursts, or reheat the entire dish in a covered skillet over medium-low heat, adding a splash of water or broth if the sauce has thickened too much.
This dish freezes well for up to 3 months. Cool completely, then transfer to freezer-safe containers or bags. Thaw overnight in the refrigerator before reheating.
Variations
Garlic Beef Strips: Add 4 cloves of minced fresh garlic or 1 tablespoon of garlic powder to the sauce mixture.
Spicy Beef Strips: Add 1 teaspoon of red pepper flakes or 2 tablespoons of sriracha to the sauce mixture. Use a spicy cream of mushroom soup if available.
Beef Stroganoff Style: After baking, stir in ½ cup of sour cream just before serving. This transforms the sauce into a creamy, tangy stroganoff.
Mushroom Lover’s: Add 8 ounces of sliced fresh cremini or button mushrooms to the casserole dish along with the beef. Sauté them briefly first for deeper flavor, though this is not required.
Lower-Sodium Version: Use low-sodium cream of mushroom soup, a low-sodium dry onion soup mix, and reduced-sodium soy sauce. Add a pinch of garlic powder and onion powder to compensate for lost flavor.
The Tax Season Philosophy
This recipe is named with affection for the time of year when cooking feels like one chore too many. Tax season is relentless. It demands long hours, sharp focus, and more coffee than is probably wise. The last thing anyone needs is a complicated recipe with a dozen ingredients and multiple steps.
This dish asks almost nothing of you. You open a few cans and packets, stir them together, pour them over beef, and put it in the oven. An hour later, dinner is ready. The beef is tender. The gravy is rich. And you did not have to stand over a stove or dirty a dozen dishes.
It is not fancy. It is not trying to be. It is dependable, comforting, and exactly what you need when you have nothing left to give. That is the spirit of Tax Season Beef Strips. And honestly, that kind of cooking is valuable all year round.
