Prep the zucchini: Slice into even pieces (about ¾-inch). This helps them cook evenly.
1 ¼ pounds chopped zucchini
Heat the skillet: Add olive oil to a large skillet over medium-high heat.
1 tablespoon olive oil
Cook the zucchini: Add in a single layer and let them sit for 1–2 minutes without stirring. This helps them brown. Then stir and continue cooking for 3–4 more minutes until just tender.
Add garlic: Stir in the minced garlic and cook another minute, being careful not to burn it.
1 tablespoon garlic
Finish with flavor: Turn off the heat. Add lemon juice, zest, green onion (if using), salt, and pepper. Stir gently to combine.
1 green onion, 1 teaspoon fresh lemon juice, ¾ teaspoon salt, 1 teaspoon lemon zest, ⅛ teaspoon black pepper
Serve: Top with Parmesan or nutritional yeast if desired and serve warm.
3 tablespoons fresh grated Parmesan cheese
