I can never resist zucchini when it turns golden brown in buttery garlic sauce with a shower of parmesan. This simple side dish looks humble, but it steals the spotlight every time.

Jump to Recipe

I’m obsessed with this Garlic and Parmesan Sauteed Zucchini because it tastes way bigger than the effort behind it. The zucchini gets those golden, savory edges I always pick at straight from the pan, and Parmesan cheese clings in all the best salty little bits.

And yes, I absolutely count this as the side dish I “sample” until half of it is gone. But honestly, it earns that kind of behavior.

It’s buttery, garlicky, a little crisp at the edges, and totally impossible for me to ignore. Simple.

Fast. Ridiculously good with whatever else I’m pretending is dinner that night.

How to Make this

Print Recipe (No Advertisments)

1. Pat zucchini dry and slice into 1/4 inch rounds.

2. Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat until shimmering.

3. Add zucchini in a single layer, working in batches if needed so pieces do not crowd the pan.

4. Season zucchini with 1/4 teaspoon kosher salt and 1/8 teaspoon black pepper, and cook undisturbed 3 to 4 minutes until the bottoms are golden brown.

5. Flip zucchini and cook the other side 2 to 3 minutes until golden and just tender, then transfer to a plate.

6. Reduce heat to medium, add remaining 1 tablespoon butter to the skillet, then add minced garlic and cook 30 to 45 seconds until fragrant, stirring so garlic does not burn.

7. Return zucchini to the skillet, toss to coat in the garlic butter, adjust salt to a total of 1/2 teaspoon if needed, and sprinkle with grated Parmesan; cook 1 minute until cheese melts into the sauce.

8. Remove from heat, stir in chopped parsley and 1 teaspoon fresh lemon juice if using, then serve immediately.

FAQ

Can I use yellow squash instead of zucchini? Yes. Use the same method and cook time; yellow squash has similar water content and flavor, so it swaps in perfectly.

How do I prevent the zucchini from turning soggy? Salt the slices and let them sit 10 minutes, then pat dry to draw out excess moisture. Cook over medium-high heat without overcrowding the pan so they brown quickly.

How long does it keep in the fridge? Store in an airtight container for up to 3 days. Reheat gently in a skillet over low heat to avoid becoming mushy.

Can I make this ahead for a dinner party? Yes. Sauté and cool, then refrigerate. Rewarm in a skillet just before serving and add the Parmesan and parsley at the end for best texture and brightness.

What can I use instead of Parmesan? Pecorino Romano or grated Asiago work well for a saltier, sharper finish. For a milder note, try finely shredded mozzarella and add at the end to melt slightly.

Is there a way to add more flavor without changing the recipe much? Add a pinch of red pepper flakes while sautéing for heat, a teaspoon of lemon zest with the juice for brightness, or toss with toasted pine nuts for texture.

Garlic And Parmesan Sauteed Zucchini Recipe Substitutions and Variations

Zucchini: use yellow summer squash or pattypan squash, sliced the same thickness and cooked until tender.
Olive oil: swap with avocado oil or light-tasting vegetable oil for a higher smoke point.
Unsalted butter: use ghee for nuttier flavor or regular salted butter, reducing added salt slightly.
Parmesan cheese: replace with Pecorino Romano for sharper saltiness or finely grated Asiago for similar texture.

Pro Tips

1. Get the zucchini really dry before cooking. Patting the rounds with paper towels removes surface moisture so they brown instead of steam, and you will get a much better crust.

2. Don’t overcrowd the pan. Work in batches if needed so each round has space to make contact with the skillet. A single crowded layer will release moisture and stay soggy.

3. Use a mix of oil and butter for flavor and heat stability. The oil raises the butter’s smoke point so you can get a hot, golden sear without burning the butter solids.

4. Finish off with the lemon and parsley right at the end. The acid brightens the dish and the fresh herb adds contrast to the rich garlic Parmesan, so add them just before serving for maximum freshness.
