Ingredients

For the Zucchini Steaks :

• 2 medium zucchini (about 1 lb total) 
• 1 teaspoon kosher salt (for drawing out moisture) 
• 4 cloves garlic, finely chopped or grated 
• ¼ teaspoon crushed red pepper flakes, plus more for serving 
• 4 tablespoons extra-virgin olive oil, divided 

For the Cheesy Topping :

• 2 oz (60g) mozzarella cheese, shredded (about ½ cup) 
• 1 oz (30g) Parmesan cheese, finely shredded (about ½ cup) 

For Garnish :

• 2 tablespoons fresh basil, torn 

Step-by-Step Instructions

Step 1: Prepare the Zucchini

Using a sharp knife, slice each zucchini in half lengthwise to create 4 “steaks” . Score the flesh side about ¼ inch deep in a diagonal crosshatch pattern at ½-inch intervals. This isn’t just for looks – it helps the zucchini cook evenly and absorb all that garlicky goodness .

Season the scored sides with 1 teaspoon of kosher salt. Let them sit for about 15 minutes . This crucial step draws out excess moisture, ensuring your zucchini steaks get a beautiful golden sear instead of steaming into sogginess. Trust me, this is the secret to a firm, meaty texture .

Step 2: Make the Garlic Oil

Preheat your oven to 425°F (220°C) and place a rack in the center .

In a large skillet over medium heat, cook the garlic, red pepper flakes, and 2 tablespoons of olive oil, stirring until the garlic becomes fragrant – this should take just 1-2 minutes . The smell will be amazing! Transfer this garlic oil to a small bowl, but don’t wash that skillet! We’re using it again .

Step 3: Sear the Zucchini Steaks

Heat another 1 tablespoon of olive oil in the same skillet over medium-high heat . Pat those zucchini steaks completely dry with paper towels (this is super important for getting a good sear!) .

Arrange 2 halves flesh-side down in the skillet and cook until they’re golden brown on the bottom, about 2-3 minutes . Transfer them to a baking sheet, placing them flesh-side up. Repeat with the remaining zucchini and the last tablespoon of olive oil .

Step 4: Bake and Add the Cheese Topping

Brush the seared zucchini steaks with that amazing garlic oil you made earlier . Pop them in the oven and bake until they’re tender in the center, about 8-10 minutes .

Top each steak with a generous amount of mozzarella and Parmesan. Don’t skimp here – this cheesy topping is what transforms these from regular zucchini to something special !

Step 5: Broil and Garnish

Turn your broiler on high. Broil the zucchini until the cheese is melted and beautifully browned, about 2-3 minutes . Watch them closely – the difference between perfectly browned cheese and burnt cheese happens in seconds !

Transfer your beautiful Cheesy Garlic Zucchini Steaks to a serving platter, top with torn fresh basil, and sprinkle with additional red pepper flakes if you like a bit more heat . Serve immediately while they’re hot and the cheese is still gooey !

5 Essential Tips for the Best Zucchini Steaks

1. Don’t Skip the Salt Rest: This is the most important step! Drawing out moisture ensures a crispy sear instead of a steamed, soggy zucchini. Letting them sit for 15 minutes is worth every second .
2. Pat Them Completely Dry: After the salt rest, use paper towels to dry the zucchini thoroughly. Any remaining moisture will prevent a good sear .
3. Use Fresh Herbs and Quality Cheese: Fresh basil at the end makes a huge difference in flavor . Also, shredding your own mozzarella and Parmesan from a block will melt much better than pre-shredded cheese, which often contains anti-caking agents .
4. Don’t Over-Broil: The broiler works fast! Stay near the oven and watch the cheese closely. You want it melted and golden, not burnt and black .
5. Serve Immediately: These zucchini steaks are best enjoyed fresh out of the oven while the cheese is still hot and melty .

Delicious Variations to Explore

• Make it Spicy: Add extra red pepper flakes to the garlic oil or sprinkle some on top for more heat .
• Add a Protein: Serve these cheesy zucchini steaks alongside your favorite grilled chicken or steak for a complete meal .
• Different Cheeses: Experiment with other cheeses like provolone, sharp cheddar, or a dairy-free alternative .
• Use Yellow Squash: If you don’t have zucchini, yellow squash makes a great substitute .

Storage and Reheating Guide

• Refrigeration: These steaks are best fresh, but they’ll keep in an airtight container in the refrigerator for up to 3 days .
• Reheating: You can reheat in the microwave or wrap them in foil and reheat them in the oven, garlic bread-style . For the best texture, reheat in a toaster oven or oven at 350°F (175°C) for about 10 minutes .

Frequently Asked Questions (FAQ)

Q: Can I make these ahead of time?
A: These zucchini steaks are best served immediately for the optimal crispy texture. However, you can prepare the garlic oil ahead of time and store it in the fridge for up to 3 days. For the best texture, prep and cook them fresh .

Q: Why did my zucchini turn out soggy?
A: This is almost always caused by not drawing out the moisture with salt or skipping the drying step before searing. The salt rest and thorough drying are non-negotiable for a crispy result .

Q: Can I make this dairy-free?
A: Yes! Simply swap the mozzarella and Parmesan for your favorite plant-based cheese alternatives .

Q: What kind of pan should I use?
A: A large skillet, preferably cast iron or stainless steel, works best for achieving a good sear . Avoid non-stick for this recipe, as you want the zucchini to develop a golden crust.
