Prepare the Zucchini: Wash the zucchini under cold water and pat them completely dry with a paper towel. This is a crucial step; excess moisture will cause the zucchini to steam instead of sear, resulting in a mushy texture. Trim off the stem and blossom ends. Cut the zucchini into uniform ¼ to ½-inch thick rounds (coins) or half-moons. Uniformity ensures even cooking.

Heat the Pan: Place a large skillet (a 12-inch cast-iron or heavy-bottomed stainless steel pan works best) over medium-high heat. Let the pan get hot for a minute or two before adding the oil.

Add the Oil: Pour 2 tablespoons of the olive oil into the hot pan. Swirl the pan to coat the bottom evenly. The oil should shimmer slightly when it’s ready.

Sauté in Batches: Carefully place a single layer of zucchini slices into the hot pan. Do not overcrowd it! This is the most important rule of sautéing zucchini. You should hear a distinct sizzle as the zucchini hits the pan. If you don’t, the pan isn’t hot enough. Cook the zucchini in 2-3 batches if necessary.

Get the Perfect Sear: Let the zucchini cook, undisturbed, for 2-4 minutes on the first side. Resist the urge to stir it constantly. This allows the slices to develop a beautiful, deep golden-brown crust. Use tongs to check one piece; if it’s well-browned, flip the slices over.

Cook the Second Side: Cook for another 2-3 minutes on the second side, until tender-crisp and browned. Remove the first batch from the skillet and set it aside on a plate.

Cook Remaining Batches: Add the remaining 1 tablespoon of olive oil to the pan if it looks dry, and repeat the process with the remaining zucchini until it is all cooked.

Combine and Infuse Flavor: Once all the zucchini is cooked, return all of it to the skillet. Reduce the heat to low. Add the minced garlic and cook for just 30-60 seconds, stirring constantly. You want the garlic to become fragrant, not browned or burnt, as burnt garlic tastes bitter.

Add Herbs and Seasoning: Turn off the heat. Immediately sprinkle the chopped fresh parsley, thyme, salt, and black pepper over the zucchini. Toss everything together gently to combine and coat the zucchini evenly in the garlic and herbs. The residual heat from the pan will wilt the herbs perfectly.

Serve Immediately: Transfer the sautéed zucchini to a serving platter. For an extra pop of flavor, you can add a squeeze of fresh lemon juice, a pinch of red pepper flakes for heat, or a sprinkle of grated Parmesan cheese. Serve warm and enjoy!
