Ingredients for Low-Carb Sautéed Zucchini with Mushrooms

Core Ingredients

Here’s everything you’ll need for this quick and tasty dish:

• Olive oil or avocado oil – Either works great, just make sure it’s good quality.

• Garlic – Freshly minced adds the most flavor.

• Zucchini – Two medium-sized, sliced into half-moons so they cook evenly.

• Mushrooms – White button or cremini work perfectly. Slice them evenly.

• Dried thyme or Italian seasoning – Adds a layer of earthy, herby depth.

• Salt and black pepper – To bring everything to life.

• Optional add-ins – A pinch of red pepper flakes for heat, chopped fresh parsley for brightness, or grated Parmesan for a savory finish.

This is the kind of recipe that welcomes flexibility, so don’t worry if you’re missing one or two extras.

Substitutions and Tips

• Oil – If you prefer, butter or ghee gives a richer flavor, especially with mushrooms.

• Garlic – No fresh garlic? Garlic powder will do in a pinch, though the fresh stuff is worth it.

• Mushrooms – Swap in shiitake, baby bellas, or even portobello strips for a more robust, meaty bite.

• Zucchini – Yellow summer squash is a great alternative or mix them for color.

• Seasoning – Don’t have Italian seasoning? Mix your own with dried basil, oregano, thyme, and rosemary.

Pro tip: Keep your mushrooms dry before cooking. Moisture is the enemy of a good sear.

Best Mushrooms for Sautéing with Zucchini

If you’re not sure which mushrooms to use, cremini (also called baby bellas) are your best bet. They’re firmer than white buttons and have a deeper, earthier flavor that holds up well to sautéing. White button mushrooms are still a solid choice—mild, tender, and budget-friendly.

Whichever type you choose, the key is to avoid washing them under water. Mushrooms soak up liquid like sponges. Instead, wipe them clean with a damp cloth or paper towel before slicing. This little step makes a big difference in texture when cooking.

Kitchen Tools You’ll Need

Must-Have Tools

You don’t need fancy equipment, just a few kitchen basics:

• A large skillet – Nonstick, stainless steel, or cast iron all work. The larger the pan, the better your veggies will brown.

• Cutting board and sharp knife – For prepping the zucchini and mushrooms.

• Garlic press or fine grater – For quick and easy garlic prep.

Nice-to-Have Tools

If you’re someone who cooks often, these tools can make life even easier:

• Mandoline slicer – Helps cut even slices of zucchini for consistent cooking.

• Silicone spatula – Gentle on nonstick surfaces and great for stirring without breaking up the veggies.

Cooking is always easier (and more enjoyable) when your tools are ready to go.

How to Make Low-Carb Sautéed Zucchini with Mushrooms

Let’s get right into it—this dish comes together quickly, so once your ingredients are prepped, it’s smooth sailing. You’ll only need one pan, a bit of attention, and maybe a little patience while the mushrooms do their thing. If you’ve never sautéed vegetables before, don’t worry. This guide walks you through each step so you’ll feel confident and ready to cook.

Step 1: Heat the Oil

Start by setting a large skillet over medium heat. Add your olive oil (or avocado oil), and give it a minute to warm up. You’ll know it’s ready when it shimmers slightly across the pan. Don’t rush this step—the right temperature is key to drawing out the best flavors.

Step 2: Sauté the Garlic

Toss in the minced garlic and stir it around for about 30 seconds. It’ll become fragrant fast—this is your cue that it’s doing its job. Be careful not to let it brown too much, or it can turn bitter. You’re just waking up the garlic here, not roasting it.

Step 3: Cook the Mushrooms

Add the sliced mushrooms to the skillet. Spread them out as evenly as you can—if they’re piled up, they’ll steam instead of brown. This is one of the most important steps. Let the mushrooms sit undisturbed for a minute or two before stirring. This helps them develop that beautiful golden color and rich, savory flavor.

Cook the mushrooms for 4 to 5 minutes, stirring occasionally. As they cook, they’ll release their moisture, shrink a bit, and start to brown around the edges. You’re looking for a slightly crisp texture with deep umami notes.

Step 4: Add the Zucchini and Seasonings

Now it’s time for the zucchini. Add the slices to the pan and give everything a good stir so the veggies get coated in that garlicky oil. Season with salt, pepper, and your choice of thyme or Italian seasoning. If you want a little heat, a pinch of red pepper flakes adds a gentle kick.

Cook the zucchini for 4 to 6 minutes, stirring occasionally. You want it to stay tender-crisp—not mushy—so don’t overdo it. The zucchini should be just soft enough to bite through, with a bit of bite left in the center.

Step 5: Garnish and Serve

Once everything is cooked to your liking, remove the skillet from the heat. If you’re using fresh parsley or grated Parmesan, now’s the time to sprinkle it on. The herbs add a fresh, bright finish, while the cheese brings a little salty depth.

Serve it up right away as a side dish, or pile it onto your plate as a light vegetarian main. Either way, you’ll be coming back for seconds.

Tips for Success

Great recipes are often made in the small details, and this one’s no exception. Here are a few extra pointers to help you get the best results every time:

• Don’t overcrowd the pan. If your skillet feels cramped, cook the mushrooms in two batches. Giving them space helps them brown instead of steam.

• Dry the mushrooms. A quick wipe with a damp paper towel keeps them from soaking up too much water.

• Add a splash of lemon juice. Right at the end, it brightens the whole dish and balances the savory flavors.

• Pair it right. This recipe goes especially well with grilled chicken, baked salmon, or a juicy steak.

How to Store Low-Carb Sautéed Zucchini with Mushrooms

Got leftovers? Here’s how to keep them tasting great the next day—or even later in the week.

At Room Temperature

Once cooked, don’t let the dish sit out for more than two hours. It’s best enjoyed hot off the stove, so serve it right away if you can.

In the Refrigerator

Store cooled leftovers in an airtight container for up to three days. Reheat gently in a skillet over low heat, or microwave in short bursts to avoid overcooking.

Freezing Tips

Freezing isn’t ideal for this dish—zucchini tends to go soft and watery after thawing. But if you do freeze it, undercook the vegetables slightly and cool them quickly before freezing. Thaw in the fridge overnight and reheat on the stove for best results.

Frequently Asked Questions

Can I make this dish ahead of time?

Absolutely. You can prep everything ahead—slice the zucchini, clean the mushrooms, even mince the garlic. Cook it fresh for the best texture, or reheat leftovers gently.

Can I add protein to make it a full meal?

Yes, and it’s a great idea. Add cooked chicken, shrimp, or tofu toward the end of cooking. You could even stir in some pre-cooked sausage or bacon for a heartier option.

What if I don’t have Italian seasoning?

No problem. Mix your own using dried oregano, basil, thyme, and rosemary. Even just a bit of dried thyme on its own still works beautifully.

Can I bake this instead of sautéing?

You sure can. Toss everything together on a sheet pan, then roast at 400°F for about 20 minutes. It’ll come out slightly different in texture but still delicious.
