Step-by-Step Cooking Instructions

Making this low-carb stir fry zucchini with mushrooms and onions is quick, easy, and perfect for a healthy meal. Follow these step-by-step instructions to achieve a perfectly cooked, flavorful dish with just the right texture.

Step 1: Gather and Prepare the Ingredients

Before you start cooking, it’s important to have all your ingredients washed, chopped, and ready to go.

How to Properly Slice the Vegetables:

• Zucchini – Cut into thin half-moons (about ¼-inch thick) for quick and even cooking.
• Mushrooms – Slice evenly to maintain texture and prevent sogginess.
• Onion – Slice thinly for a mild, caramelized flavor.

Pro Tip: Pat dry zucchini slices with a paper towel to remove excess moisture and prevent a soggy stir-fry.

Step 2: Heat the Pan & Add Oil

• Use a large skillet, wok, or cast-iron pan for the best results.
• Heat 1 tablespoon of olive oil, avocado oil, or butter over medium-high heat until hot but not smoking.

Step 3: Sauté the Onions & Mushrooms

• Add the sliced onions first and cook for 2-3 minutes, stirring occasionally until they turn soft and slightly golden.
• Add the mushrooms and cook for another 3-4 minutes until they release their moisture and start to brown.
• Stir in minced garlic and cook for 30 seconds, until fragrant.

Pro Tip: Avoid overcrowding the pan—this helps the mushrooms caramelize instead of steaming.

Step 4: Add the Zucchini & Seasonings

• Push the onions and mushrooms to the side and add sliced zucchini to the pan.
• Stir-fry for 4-5 minutes, stirring occasionally. The zucchini should be tender but still slightly crisp.
• Sprinkle with salt, black pepper, and red pepper flakes (if using).
• Pour in 1 tablespoon of soy sauce or tamari for an extra umami boost.

Pro Tip: If you want a little extra crunch, cook the zucchini for less time (about 3 minutes).

Step 5: Finish & Serve

• Once the zucchini is tender but not mushy, remove the pan from heat.
• (Optional) Sprinkle with sesame seeds or a splash of lemon juice for extra flavor.
• Serve hot as a side dish or add protein (chicken, shrimp, or tofu) to make it a complete meal.

Tips for the Best Stir Fry

A great stir fry is all about perfectly cooked vegetables, balanced flavors, and the right cooking technique. Follow these expert tips to make sure your low-carb zucchini, mushroom, and onion stir fry turns out flavorful and crisp every time!

1. Prevent Zucchini from Getting Soggy

• Slice evenly: Cut zucchini into ¼-inch half-moons to ensure even cooking.
• Pat dry before cooking: Zucchini contains a lot of water—use a paper towel to remove excess moisture.
• Cook on high heat: Stir-frying over high heat prevents the zucchini from releasing too much water.
• Add zucchini last: Since zucchini cooks quickly, add it after mushrooms and onions have softened.

2. Use the Right Cooking Oil

• Use high smoke point oils like avocado oil, olive oil, or butter for best results.
• Avoid oils with a low smoke point (like flaxseed oil), as they burn easily.

3. Cook in the Right Order

• Start with onions – They take longer to soften and release a mild sweetness.
• Add mushrooms next – They release moisture and need more time to brown.
• Add zucchini last – It cooks quickly and should remain slightly crisp.

4. Don’t Overcrowd the Pan

• Overcrowding leads to steaming instead of stir-frying. Use a large skillet or wok to allow the veggies to cook evenly.

5. Season at the Right Time

• Add salt and soy sauce toward the end to prevent excessive water release.
• Enhance flavor with garlic, red pepper flakes, or a splash of lemon juice.

• Chicken: Sauté thinly sliced chicken breast or thighs before cooking the vegetables.
• Shrimp: Toss in shrimp during the last few minutes of cooking for a quick, high-protein option.
• Beef: Thinly sliced steak (such as flank or sirloin) works well with the stir-fry method.
• Tofu: For a vegetarian option, use crispy pan-fried tofu.

2. Try Different Low-Carb Sauces

For a new twist on flavor, swap out soy sauce for:

• Garlic Butter Sauce: Melt butter with minced garlic for a rich, buttery flavor.
