Ingredients You’ll Need
- 2 lbs. cheap steaks: Look for cuts like petite sirloins for maximum tenderness on a budget. If you prefer, flank steak or chuck roast also works well.
- 2 white or yellow onions: Sliced into circles; they become sweet and caramelized as they cook, enhancing the dish’s overall flavor.
- ½ tsp. salt: Just the right amount to season the steak and help bring out its natural flavors.
- ¼ tsp. pepper: Freshly ground enhances taste and adds a delightful kick.
- 1 Tbsp. minced garlic: Fresh garlic adds a fragrant touch that elevates the dish.
- 0.70 oz. Italian dressing mix packet: This mix infuses the steak with zesty flavor. You can substitute with homemade Italian seasoning if desired.
- 0.87 oz. brown gravy mix: For a rich, savory sauce that binds everything together. No worries if you want to make it from scratch; just use beef broth instead.
- 1 ½ cups water: Helps create a flavorful gravy as everything simmers together.
- 3 Tbsp. cornstarch: This thickens the gravy at the end for a luscious finish, though flour is a substitute options if preferred.
How to Make Slow Cooker Steak and Onions
- Prepare the Meat: Place the 2 lbs. of cheap steaks in the bottom of your slow cooker and sprinkle with ½ tsp. salt and ¼ tsp. pepper. The seasoning is essential for flavor balance.
- Layer the Aromatics: Top the steak with the 2 sliced onions and 1 Tbsp. minced garlic. The garlic becomes a fragrant addition as it cooks, and the onions turn beautifully sweet.
- Mix the Sauce: In a small bowl, combine the 0.70 oz. Italian dressing mix, 0.87 oz. brown gravy mix, and 1 ½ cups water. Whisk until well combined, allowing the flavors to meld.
- Combine Everything: Pour the mixture over the steak and onions in the slow cooker, ensuring even coverage for optimal flavor infusion.
- Slow Cook to Perfection: Cook on LOW heat for 5-6 hours until the steak is tender, and the onions are caramelized. You’ll know it’s ready when the meat easily shreds with a fork.
- Thicken the Gravy: If you prefer a thicker sauce, mix 3 Tbsp. of cornstarch with equal parts water until smooth, then stir it into the slow cooker about 30 minutes before serving. This will create a beautifully rich gravy!
Storing & Reheating
Once your Steak and Onions has cooled, store any leftovers in an airtight container in the refrigerator for up to 3-4 days. If you want to save it for later, you can freeze portions for up to 3 months. When you reheat, do so gently on the stovetop or in a microwave, ideally at low power, checking regularly until it reaches an appropriate temperature. The texture may change slightly once frozen and reheated, so stir in a bit of water or beef broth to refresh the consistency.
Chef’s Helpful Tips
- Ensure your steaks are evenly seasoned with salt and pepper to avoid blandness.
- When layering ingredients in the slow cooker, don’t overcrowd the onions; they caramelize better when they have space to breathe.
- If you want to amp up the flavors, marinate the steak in the Italian dressing mix overnight for deeper taste.
- Feel free to experiment with other vegetables like bell peppers or mushrooms; just add them during the last hour of cooking.
- If you prefer a more robust sauce, add a splash of red wine or balsamic vinegar to the sauce mixture for depth.
Embrace the simplicity of this slow-cooked delight—we all need that one recipe we can whip up and be confident everyone will love it. The combination of juicy steaks with the flavorful onion gravy is a guaranteed hit at the dinner table.
Enjoy every bite, savor your time together with family or friends, and don’t hesitate to make this recipe your own with little tweaks here and there!
