Cheesy Garlic Zucchini Steaks

Crispy, tender, and loaded with bubbly mozzarella, these cheesy garlic zucchini steaks are the ultimate low-carb side dish. Easy, fast, and family-approved!

Why This Recipe Works:

• Osmotic dehydration (salting) removes excess water, ensuring a meaty, firm texture instead of a soggy mess.
• High-heat roasting triggers the Maillard reaction, caramelizing the natural sugars in the zucchini.
• A blend of low-moisture mozzarella and sharp parmesan creates a bubbly, golden cheese crust that clings perfectly to the seasoned surface.

I still remember the humid Tuesday evening I tried to grill zucchini for my family, only to watch the limp, waterlogged green slabs slip right through the grates into the ash below.

It was humiliating.

The fundamental issue with zucchini is its staggering 95% water content, which turns a promising side dish into a soggy, mushy disappointment the second heat is applied. Bear with me here, because this is pure physics: if you do not draw out that excess moisture before baking, the steam trapped inside the vegetable will push away any cheese or garlic topping you try to melt over it, leaving you with a watery puddle on your baking sheet.

My simple fix is a quick salt-sweat method that draws out the water through osmosis, followed by a hard roast at high heat to caramelize the edges.

This technique works beautifully for other vegetables too, much like how we prep our savory golden crusted cheesy cauliflower steaks or even our roasted cabbage steaks.

Ingredients

• 3 medium zucchinis, sliced lengthwise into 1/2-inch "steaks"
• 1 teaspoon Diamond Crystal kosher salt (or 1/2 teaspoon fine sea salt)
• 2 tablespoons extra virgin olive oil
• 3 cloves garlic, finely minced
• 1 teaspoon Italian seasoning
• 1/2 teaspoon freshly cracked black pepper
• 1 cup low-moisture shredded mozzarella cheese
• 1/4 cup freshly grated Parmesan cheese
• Fresh chopped parsley, for garnish

Directions

1. Slice the zucchinis lengthwise into 1/2-inch thick slabs, discarding the outer rounded edges.
2. Lay the zucchini slices on a clean kitchen towel or paper towels, sprinkle evenly with the kosher salt, and let them sit for 10 minutes to draw out excess moisture.
3. Firmly press another paper towel over the zucchini steaks to blot away the beaded water droplets.
4. Preheat your oven to 425°F (218°C) and line a large baking sheet with parchment paper.
5. In a small bowl, whisk together the olive oil, minced garlic, Italian seasoning, and black pepper.
6. Brush both sides of the zucchini steaks with the garlic oil mixture and arrange them in a single layer on the prepared baking sheet.
7. Roast for 12 to 15 minutes until the zucchini is tender-crisp and starting to brown at the edges.
8. Remove from the oven, top each steak generously with the shredded mozzarella and grated Parmesan, then return to the oven under the broiler for 2 to 3 minutes until the cheese is bubbly and golden brown.

Notes

• I highly recommend using Diamond Crystal kosher salt for sweating the zucchini; if you only have standard table salt, cut the measurement in half (use 1/2 teaspoon) to avoid an overly salty dish.
• Sweating the zucchini is not optional. The salt draws out water via osmosis, which prevents the vegetable from steaming itself in the oven and ensures the cheese crust clings to the steak instead of sliding off.
• Keep a close eye on the garlic during the initial roasting phase; if minced too finely, garlic can burn easily at 425°F, turning bitter and ruining the delicate flavor profile.
• Leftover zucchini steaks will lose their crispness in the fridge as the cellular walls continue to break down, so plan to reheat them under a broiler rather than in the microwave.

Serving Suggestions

These cheesy zucchini steaks are incredibly versatile and pair beautifully with a variety of mains. Here are a few of our favorite ways to serve them:

• Serve alongside a juicy baked chicken breast for a wholesome, low-carb dinner.
• Pair with our savory garlic butter steak bites to create a steakhouse-style meal at home.
• Use them as a gluten-free base for a quick vegetarian meal, similar to how you would enjoy chicken parmesan zucchini boats.
• Plate them next to a fresh, crisp salad to balance out the rich, bubbly cheese crust.

Storage and Reheating

Store leftovers in an airtight container.

They will keep in the refrigerator for up to three days, though they will naturally soften over time as the moisture redistributes. Avoid freezing them entirely, as freezing destroys the vegetable's cellular structure, leaving you with a mushy mess upon thawing.

To reheat, place the steaks on a baking sheet and broil for 3 to 4 minutes.

This direct, dry heat melts the cheese back to its bubbly glory while crisping up the edges of the zucchini. Avoid the microwave at all costs unless you enjoy rubbery cheese and soggy vegetables.

Ingredient Substitutes

If you need to swap ingredients based on what is in your pantry, here are some easy alternatives:

1. Zucchini: Yellow summer squash works as an identical 1:1 substitute, offering a slightly sweeter flavor profile.
2. Mozzarella: Provolone or Monterey Jack can be used instead of mozzarella for a similarly gooey melt.
3. Parmesan: Pecorino Romano or Asiago cheese will provide that same sharp, salty bite to the crust.
4. Garlic: If fresh garlic isn't on hand, substitute with 1/2 teaspoon of garlic powder mixed into the olive oil.
