Let’s dive into the step-by-step preparation of this flavorful Keto Beef and Mushroom Stir-Fry with Spinach!
Ingredients:
For the Stir-Fry:
- 1 pound (450g) beef (ribeye, sirloin, or flank steak), thinly sliced
- 2 cups mushrooms (button, cremini, or shiitake), sliced
- 2 cups fresh spinach, washed and dried
- 2 tablespoons avocado oil or olive oil
- 2 cloves garlic, minced
- 1 teaspoon fresh ginger, grated
- ½ teaspoon red pepper flakes (optional, for spice)
For the Keto Stir-Fry Sauce:
- 2 tablespoons soy sauce or tamari (for gluten-free option)
- 1 tablespoon coconut aminos (for a hint of natural sweetness)
- 1 teaspoon sesame oil
- ½ teaspoon xanthan gum (optional, for thickening)
- ½ teaspoon fish sauce (for extra umami, optional)
- 1 teaspoon apple cider vinegar or rice vinegar
- ½ teaspoon black pepper
- ½ teaspoon salt (adjust as needed)
Preparation:
Step 1: Prepare the Ingredients
- Slice the beef into thin strips against the grain. This helps make the meat tender and easier to chew.
- Wash and slice the mushrooms evenly. If using shiitake mushrooms, remove the tough stems.
- Rinse and dry the spinach. Set aside.
- Mince the garlic and grate the fresh ginger.
Step 2: Make the Stir-Fry Sauce
- In a small bowl, combine soy sauce, coconut aminos, sesame oil, fish sauce (if using), apple cider vinegar, black pepper, and salt.
- If using xanthan gum for thickening, whisk it into the sauce until well combined.
- Set the sauce aside for later use.
Step 3: Cook the Beef
- Heat 1 tablespoon of avocado oil in a large skillet or wok over medium-high heat.
- Add the sliced beef to the pan in a single layer. Let it sear for 1-2 minutes before stirring.
- Stir-fry for another 2-3 minutes until the beef is browned and cooked through.
- Remove the beef from the pan and set it aside on a plate.
Step 4: Sauté the Vegetables
- Add the remaining 1 tablespoon of oil to the pan.
- Toss in the minced garlic and grated ginger. Sauté for about 30 seconds until fragrant.
- Add the sliced mushrooms and cook for 3-4 minutes, stirring occasionally, until they are tender and slightly caramelized.
Step 5: Combine Everything
- Return the cooked beef to the pan with the mushrooms.
- Pour the prepared stir-fry sauce over the beef and mushrooms. Stir well to coat everything in the sauce.
- Add the fresh spinach and stir for 1-2 minutes until it wilts.
- Taste and adjust seasoning if needed.
Variations
- Protein Options: Substitute beef with chicken, shrimp, or tofu for a different protein source.
- Veggie Additions: Try adding bell peppers, zucchini, or broccoli for more variety.
- Extra Spice: Increase the heat with extra red pepper flakes or a splash of sriracha.
- Nutty Flavor: Add a handful of toasted sesame seeds or chopped almonds for crunch.
Cooking Notes:
- Thin Slicing the Beef: The thinner the beef slices, the faster and more evenly they cook. Freezing the beef for about 15 minutes before slicing can help achieve paper-thin cuts.
- High Heat Cooking: Stir-frying works best over high heat to quickly sear the ingredients while keeping them tender and juicy.
- Avoid Overcooking the Spinach: Spinach wilts quickly, so add it at the very end to maintain its texture and nutrients.
Serving Suggestions:
- Serve this Keto Beef and Mushroom Stir-Fry as a standalone dish for a light yet filling meal.
- Pair it with cauliflower rice or zucchini noodles for a more substantial keto-friendly dinner.
- Garnish with sesame seeds and chopped green onions for extra flavor and presentation.
Tips:
- Meal Prep Friendly: You can slice the beef and prepare the sauce in advance for quick cooking.
- Use a Wok if Available: A wok distributes heat more evenly and allows for better stir-frying.
- Balance the Flavors: Adjust the salt, vinegar, and spice levels to match your preference.
- Low-Carb Thickening Options: If you don’t want to use xanthan gum, you can reduce the sauce slightly over heat for natural thickening.
