What You’ll Need

Ingredients

• 2 medium zucchini – Sliced into half-moons. Don’t peel them; the skin adds texture.
• 1 cup mushrooms – Sliced. Button or cremini work best, but use what you have.
• 3 cloves garlic – Minced. Fresh is best, but jarred garlic works in a pinch.
• 2 tbsp unsalted butter – If you only have salted butter, just adjust the salt later.
• 1 tbsp olive oil – Helps keep the butter from burning.
• ½ tsp salt – Or to taste.
• ½ tsp black pepper – Freshly ground is best.
• ½ tsp red pepper flakes – Optional, for a bit of heat.
• ½ tsp dried oregano or thyme – Adds a subtle earthy note.
• 1 tbsp grated Parmesan – Optional, but adds a nice salty finish.

Step-By-Step Cooking Guide

Step 1: Get Everything Ready

Before turning on the stove, chop your zucchini and mushrooms. The zucchini should be cut into half-moons—not too thin, or they’ll get mushy. Mushrooms? Just slice them evenly so they cook at the same rate.

Garlic should be minced very fine. If you like a stronger garlic flavor, you can even smash it with the side of your knife before mincing.

Set everything near your stove. Stir-fries move fast, so you don’t want to be scrambling to grab things.

Step 2: Heat the Pan

Use a large skillet or a cast-iron pan if you have one. The trick to good stir-fried vegetables is high heat.

• Place the pan over medium-high heat.
• Add olive oil and 1 tbsp of butter. The oil helps keep the butter from burning.
• Once the butter melts and starts to foam, you’re ready to cook.

Step 3: Cook the Mushrooms First

Mushrooms release a lot of water, so they need time to brown properly.

• Add the sliced mushrooms to the hot pan.
• Let them sit for about 2 minutes before stirring. This helps them develop a golden crust.
• Stir occasionally and cook for 5 minutes until they’re browned and have shrunk down.
• Remove them from the pan and set them aside.

Step 4: Cook the Zucchini

Now that the mushrooms are done, it’s time for the zucchini.

• Add another tablespoon of butter to the pan.
• Toss in the zucchini slices. Spread them out so they’re in a single layer as much as possible.
• Let them cook undisturbed for 2 minutes, so they get a bit of color.
• Stir and cook for another 3 minutes, until they’re tender but not mushy.

Step 5: Add the Garlic and Seasoning

Here’s where everything comes together.

• Add the minced garlic and stir quickly. Garlic burns fast, so keep it moving.
• Add the cooked mushrooms back into the pan.
• Season with salt, black pepper, red pepper flakes, and oregano.
• Stir for another minute, just until everything is coated in that garlicky butter goodness.

Step 6: Finish and Serve

Turn off the heat. If you’re using Parmesan cheese, sprinkle it over now while the pan is still warm.

Taste and adjust seasoning if needed. Want it spicier? Add more red pepper flakes. Love garlic? Add a bit more next time.

Serve hot, right out of the pan.

Ways to Enjoy This Dish

This stir-fry is fantastic on its own, but here are a few ways to make it even better:

• As a Side – Serve it with grilled chicken, steak, or salmon.
• With Eggs – Toss leftovers with scrambled eggs for an easy breakfast.
• As a Meal – Add cooked shrimp, diced chicken, or even crumbled sausage for extra protein.
• Over Cauliflower Rice – A full keto meal in one bowl.

Pro Tips for the Best Stir-Fry

1. Use High Heat – This keeps everything from getting soggy. You want a bit of char on those veggies.
2. Don’t Overcrowd the Pan – If the pan is too full, everything will steam instead of browning.
3. Garlic Burns Fast – Always add it last and stir constantly.
4. Fresh Ingredients Matter – Fresh zucchini and mushrooms have more flavor and better texture than ones that have been sitting in the fridge for too long.

How to Store and Reheat

If you have leftovers (which is rare because this dish is too good), here’s what to do:

• Store in the fridge for up to 3 days in an airtight container.
• Reheat in a skillet over medium heat with a little butter or olive oil. Microwaving works, but the texture won’t be as good.

Conclusion

If you ever thought vegetables were boring, this Garlic Butter Zucchini & Mushroom Stir-Fry will change your mind. It’s fast, full of flavor, and ridiculously easy to make. Whether you’re following a keto lifestyle or just want a tasty way to eat more veggies, this recipe delivers.

So go ahead, grab those zucchini and mushrooms, and get cooking. You won’t regret it.
