What Are Zucchini Steaks?
Zucchini steaks are simply zucchini cut lengthwise into thick halves that resemble the shape of a steak. The surface is lightly scored with a knife to help seasonings and oils soak deep into the vegetable while also creating a beautiful presentation.
Unlike regular sliced zucchini, zucchini steaks have a meatier texture and hold up wonderfully during searing and baking. When topped with cheese and garlic oil, they become rich, satisfying, and incredibly delicious.
This keto version combines crispy golden zucchini with melty mozzarella and salty Parmesan for the ultimate comfort food experience.

Ingredient Notes

Garlic
Fresh garlic is essential here. It creates the rich aromatic flavor that makes this dish irresistible.
Parmesan Cheese
Parmesan adds a salty, nutty flavor and helps create a crispy golden topping.
Mozzarella Cheese
Mozzarella melts beautifully and gives the zucchini steaks that gooey, cheesy finish everyone loves.
Red Pepper Flakes
These add a subtle heat that balances the richness of the cheese.
Basil
Fresh basil adds brightness and freshness to the final dish.
How to Make Keto Cheesy Garlic Zucchini Steaks
Step 1: Prepare the Zucchini
Wash and dry the zucchini thoroughly. Using a sharp knife, slice each zucchini lengthwise to create four zucchini “steaks.”
Carefully score the flesh side of each zucchini half by making diagonal cuts about half an inch apart and roughly a quarter inch deep. Rotate the zucchini and repeat the cuts in the opposite direction to create a crosshatch pattern.
This scoring technique helps the zucchini absorb flavor while also allowing moisture to escape during cooking.
Sprinkle the flesh side generously with kosher salt and let the zucchini rest for about 15 minutes. You’ll notice beads of moisture forming on the surface.
Pat the zucchini dry with paper towels before cooking.
Step 2: Preheat the Oven
Preheat your oven to 425°F (220°C) and position the oven rack in the center.
A hot oven is important because it helps the zucchini cook quickly without becoming mushy.
Step 3: Make the Garlic Oil
Place a small saucepan over medium heat. Add 2 tablespoons of olive oil, the garlic, and crushed red pepper flakes.
Cook gently for a few minutes until the garlic becomes fragrant. Stir frequently to prevent burning.
The garlic should become aromatic and lightly golden, not dark brown. Burned garlic can create a bitter flavor that overpowers the dish.
Remove the saucepan from heat and pour the garlic oil into a small bowl.
Step 4: Sear the Zucchini
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
Place two zucchini steaks flesh-side down into the hot skillet. Cook for 2–3 minutes or until golden brown.
Repeat with the remaining zucchini steaks, adding the final tablespoon of olive oil if necessary.
This quick sear adds incredible flavor and gives the zucchini a delicious caramelized texture.
Step 5: Bake the Zucchini
Transfer the zucchini steaks onto a baking sheet with the flesh side facing upward.
Brush or spoon the prepared garlic oil evenly over each zucchini steak, making sure it gets into the scored cuts.
Bake for approximately 12 minutes until the zucchini becomes tender.
Step 6: Add the Cheese
Remove the baking sheet from the oven and sprinkle Parmesan and mozzarella cheese generously over each zucchini steak.
Return the baking sheet to the oven and bake for another few minutes until the cheese melts completely and turns golden brown.
For an extra crispy cheesy topping, you can broil the zucchini for 1–2 minutes at the end.
Step 7: Garnish and Serve
Transfer the zucchini steaks to a serving platter.
Top with fresh torn basil and additional red pepper flakes for extra flavor and color.
Serve immediately while the cheese is hot and bubbly.
Tips for the Best Zucchini Steaks
Salt the Zucchini First
This step is extremely important because zucchini naturally contains a lot of water. Salting helps draw out excess moisture so the zucchini becomes golden and flavorful instead of soggy.
Don’t Skip the Searing
Searing creates a rich caramelized flavor and improves the overall texture.
Watch the Garlic Carefully
Garlic cooks quickly and can burn in seconds. Keep the heat moderate and stir often.
Use Fresh Cheese
Freshly shredded cheese melts better and tastes far superior to pre-packaged shredded cheese.
Serve Immediately
These zucchini steaks taste best fresh out of the oven when the cheese is perfectly melted.
Serving Suggestions
These keto cheesy garlic zucchini steaks pair wonderfully with many dishes.
Serve them alongside:
- Grilled chicken
- Steak
- Salmon
- Roasted shrimp
- Keto burgers
- Cauliflower rice
- Fresh green salad
They also make a delicious vegetarian main course on their own.
Storage Instructions
Although best enjoyed fresh, leftovers can still be delicious.
Store any remaining zucchini steaks in an airtight container in the refrigerator for up to 3 days.
To reheat:
- Microwave for quick reheating
- Or wrap in aluminum foil and warm in the oven until heated through
Keep in mind that reheated zucchini may become slightly softer.
Frequently Asked Questions
Why Do You Salt the Zucchini Before Cooking?
Salting removes excess moisture from the zucchini. This helps the zucchini sear properly and prevents it from becoming watery during baking.
Can I Make This Recipe Ahead of Time?

Can I Use Other Cheeses?
Absolutely. Cheddar, provolone, gouda, or fontina all work wonderfully in this recipe.
Is This Recipe Vegetarian?
Yes, this recipe is completely vegetarian and keto-friendly.
Can I Cook These in an Air Fryer?
Yes. Air fry at 400°F for about 10–12 minutes, then add the cheese and cook until melted and golden.
