• 2 tablespoons butter
• 1 medium yellow onion, chopped
• 8 ounces white button mushrooms, stems trimmed and quartered

Cooking Directions

1. Chop the medium yellow onion.
2. Trim stems and quarter the mushrooms.
3. Cut the zucchini into bite-size chunks.
4. Mince the garlic.
5. Heat olive oil and butter in a large skillet over medium-high heat until the butter is melted and bubbly.

Pro Tips for Texture and Flavor

• Slice the zucchini into chunks instead of thin rounds. This keeps the texture crisp and not mushy. For a completely different result using paper-thin slices, try Italian zucchini scarpaccia.
• Don’t crowd the pan when cooking—work in batches if needed. The mushrooms and onions go first since they hold up better to cooking and brown nicely.
• If you’d like, swap zucchini for yellow squash for a slightly different but just as tasty twist.
• You can season with nearly any herbs you love—try parsley, dill, rosemary, basil, thyme, or dried oregano and marjoram. Just avoid fresh oregano and marjoram because they tend to be a bit bitter.
• Spices like paprika, cumin, cayenne, and coriander bring another layer of flavor if you want to mix things up.
• Store leftovers tightly sealed in the fridge for 3 to 4 days. Reheat carefully in the microwave at low power to avoid overcooking.
• Zucchini is mostly water, so freezing the cooked dish tends to make it mushy. If you do freeze leftovers, consider blending them into soups or sauces instead of reheating as is.

Vegetable Swaps & Add-Ins

Feeling like getting a little creative? So many veggies play well with zucchini in a sauté. Think carrots, cabbage, tomatoes, bell peppers, broccoli, spinach, parsnips, asparagus, turnips, or even eggplant. Just keep an eye on cooking times—denser vegetables might need a head start, and it’s best to cook veggies in batches or separate pans to keep that perfect texture without overcrowding your skillet.

Sauteed Zucchini Recipe

This 15-minute low-carb sautéed zucchini recipe combines onions, mushrooms, zucchini, and garlic with a perfect blend of herbs and spices into the best side dish ever.

Ingredients

• 1 tablespoon olive oil
• 2 tablespoon butter
• 1 medium yellow onion chopped
• 8 ounces white button mushrooms stems trimmed and quartered
• 3 medium zucchini cut into bite size chunks
• 2 cloves garlic minced
• 1 teaspoon Italian seasoning
• ¼ teaspoon red pepper flakes more or less to taste
• Kosher salt and fresh ground black pepper to taste

Instructions

• Heat the olive oil and butter in a large skillet over medium-high heat until melted and hot. Add the mushrooms and onions and cook until golden and lightly browned. Remove and plate them. If the skillet looks dry, add a splash more olive oil and return the heat to medium-high.
• Add the zucchini chunks, spreading them out in a single layer. Cook until they get some nice browning, tossing occasionally. Lower the heat to low, then stir in the garlic, Italian seasoning, and red pepper flakes. Mix well to coat.
• Season with kosher salt and freshly ground black pepper to your taste. Serve warm right away for the best texture. Enjoy!

Notes

• Chunky cuts of zucchini keep it crisp and tender without turning mushy.
• Cook your veggies in batches so the pan doesn’t get crowded. Mushrooms and onions go first since they take longer to soften.
• You can easily swap yellow squash for zucchini if that’s what you have handy.
• Feel free to play with herbs—parsley, dill, rosemary, basil, thyme are all great choices. Stick to dried oregano and marjoram only, as the fresh versions can be bitter.
• Adding spices like paprika, cumin, cayenne, or coriander can give the dish a nice kick.
• Keep leftovers sealed tight in the fridge for up to 3 days. Warm them gently in the microwave on low power so they don’t overcook.
• Because zucchini is mostly water, freezing this dish usually changes the texture. Try freezing leftovers as purees for soups or sauces instead.

Storing and Reheating

Got leftovers? Store them in an airtight container in the fridge for up to 3 or 4 days. When reheating, do it gently so your sautéed zucchini stays crisp-tender and doesn’t turn mushy:

• Microwave: heat at half to 70% power in short 30- to 45-second bursts, stirring in between to warm evenly.
• Stovetop: warm in a skillet over medium heat with a small drizzle of olive oil. This method helps bring back some of the original caramelization and texture.

For make-ahead cooking, you can chop all your veggies ahead of time and keep them in the fridge until you’re ready to cook. You can even cook the mushrooms and onions earlier and reheat or finish off with the zucchini and seasonings just before serving.

Freezing sautéed zucchini isn’t ideal because zucchini is about 95% water and can get mushy and watery once thawed. If freezing can’t be avoided, blend the cooked zucchini into a puree to use later in soups or sauces instead of trying to reheat it as a side dish.

Common Questions

• Q: Can I swap yellow squash for zucchini?

  A: Absolutely! Yellow squash works great as a substitute and cooks up with a similar texture and timing.

• Q: How do I stop my sautéed zucchini from getting soggy?

  A: Cut the zucchini into chunks rather than thin slices, cook it over medium-high heat, and don’t crowd the pan. Cooking in batches helps the pieces brown nicely instead of steaming.

• Q: Can I make this recipe vegan?

  A: Yes, just swap the butter for extra olive oil or your favorite vegan butter to keep it dairy-free.

• Q: What mushrooms and herbs can I use?

  A: You can use cremini, baby bella, or white button mushrooms—whatever you have on hand that cooks quickly. For herbs, try parsley, basil, thyme, rosemary, or dill. Avoid fresh oregano and marjoram, as they can be bitter.

• Q: Is it okay to add cheese?

  A: A sprinkle of Parmesan cheese at the end adds a lovely touch of savory richness without overpowering the dish. If you’re craving a cheesier, heartier zucchini main, try Chicken Mozzarella Stuffed Zucchini Boats.

• Q: Can I freeze leftover cooked zucchini?

  A: It’s not the best idea since freezing changes the texture. If you do freeze it, plan to use it blended into soups or sauces rather than reheating as a standalone side.
