Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Main ingredients:
3 medium zucchinis (about 6–7 inches long each, approximately 1 1/2 pounds total)
2 tablespoons olive oil
4 garlic cloves, finely minced
1/2 teaspoon sea salt
1/4 teaspoon freshly ground black pepper
1/4 teaspoon crushed red pepper flakes (optional)
Cheese topping:
1 cup shredded part-skim mozzarella cheese (about 4 ounces)
1/2 cup freshly grated Parmesan cheese (about 2 ounces)
1 teaspoon Italian seasoning
1 tablespoon fresh parsley, finely chopped
Directions
Step 1: Prepare the zucchini
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or a silicone baking mat. Wash and thoroughly dry the zucchinis. Trim off both ends. Slice each zucchini lengthwise into thick slabs, about 1/2 to 3/4 inch thick. You should get approximately 3 slices per zucchini, depending on size.
Step 2: Season the zucchini
Arrange the zucchini steaks in a single layer on the prepared baking sheet. In a small bowl, combine the olive oil, minced garlic, sea salt, black pepper, and crushed red pepper flakes if using. Brush or spoon the mixture evenly over both sides of each zucchini slice.
Step 3: Bake
Place the baking sheet in the preheated oven. Bake for 15 to 18 minutes, flipping the zucchini halfway through cooking. The edges should begin to turn lightly golden, and the centers should be tender while still holding their shape.
Step 4: Add the cheese topping
In a small bowl, mix together the shredded mozzarella, grated Parmesan, and Italian seasoning. Remove the zucchini from the oven and evenly sprinkle the cheese mixture over each slice.
Step 5: Broil
Turn the oven to broil. Return the zucchini steaks to the oven and broil for 2 to 3 minutes, or until the cheese is melted, bubbly, and golden brown. Watch closely to prevent burning.
Step 6: Garnish and serve
Remove from the oven and allow to cool slightly for 1 to 2 minutes. Sprinkle with freshly chopped parsley and serve warm.
Optional air fryer method:
Preheat the air fryer to 390°F (200°C). Air fry the seasoned zucchini for 8 to 10 minutes, flipping halfway through. Add the cheese mixture and air fry for an additional 2 to 3 minutes, until melted and lightly browned.
Servings and timing
Servings: 6 servings (approximately one zucchini steak per serving)
Prep time: 10 minutes
Cook time: 18 to 21 minutes
Total time: Approximately 30 minutes
Variations
For a sharper flavor, substitute shredded cheddar or Gruyère for the mozzarella.
Add thinly sliced mushrooms or cherry tomatoes on top before baking for extra texture and flavor.
For a spicier version, increase the crushed red pepper flakes to 1/2 teaspoon or add a pinch of chili powder.
To make it dairy-free, use a plant-based shredded cheese alternative and a dairy-free Parmesan substitute.
For added protein, sprinkle cooked shredded chicken or crumbled turkey over the zucchini before adding the cheese.
Storage/Reheating
Store leftover zucchini steaks in an airtight container in the refrigerator for up to 3 days.
To reheat, place them in a preheated oven at 350°F (175°C) for 8 to 10 minutes or in an air fryer at 350°F for 4 to 6 minutes until heated through. This helps maintain their texture.
Avoid microwaving if possible, as it can make the zucchini soft and watery.
Freezing is not recommended because zucchini has a high water content and may become mushy after thawing.
FAQs
Can I make zucchini steaks ahead of time?
Yes. You can slice and season the zucchini in advance and refrigerate for up to 24 hours before baking. Add the cheese just before cooking for best results.
How do I keep zucchini from becoming soggy?
Slice the zucchini thickly and avoid overcrowding the pan. Baking at a high temperature and flipping halfway through helps remove excess moisture.
Can I grill these instead of baking?
Yes. Grill the seasoned zucchini over medium heat for about 4 to 5 minutes per side, then add cheese and close the lid briefly until melted.
What proteins pair well with this dish?
Grilled chicken breast, baked salmon, steak, turkey cutlets, or roasted lamb all pair beautifully with these zucchini steaks.
Is this recipe suitable for keto diets?
Yes. Each serving contains approximately 3 grams of net carbohydrates, making it appropriate for keto and low-carb meal plans.
Can I use pre-shredded cheese?
You can, but freshly shredded cheese melts more smoothly and evenly because it does not contain anti-caking agents.
How thick should I slice the zucchini?
Aim for slices that are 1/2 to 3/4 inch thick. Thinner slices may become too soft during baking.
Can I add breadcrumbs on top?
If you are not following a low-carb diet, you may add a light sprinkle of seasoned breadcrumbs before broiling for extra crunch.
What if I don’t have Italian seasoning?
You can substitute with a mix of dried oregano, basil, and thyme in equal amounts.
Can I turn this into a main dish?
Yes. Serve two or three zucchini steaks per person and pair with a side salad or cauliflower mash for a satisfying light meal.
