Keto Pepperoni Zucchini Pizza Boats

Last summer, I was standing in my kitchen staring at a pile of zucchinis from the farmers market, wondering how many ways I could eat them before they went soft. My partner mentioned they were craving pizza, and suddenly it hit me—why not hollow them out and turn them into little edible boats? That first attempt was messy and imperfect, but when the cheese got all golden and bubbly, something clicked. Now these zucchini boats are what I reach for when I want pizza satisfaction without the carb guilt.

I made these for my sister last month when she mentioned she was trying to cut carbs, and watching her face when she bit into one was absolutely worth the effort. She expected a weird health food substitute, but instead got something that genuinely tasted like her favorite indulgence. That's when I realized these aren't just a workaround—they're actually better than regular pizza in some ways, because you get that tender vegetable base instead of dough.

Ingredients

• Medium zucchinis (4): The foundation of everything, and their water content becomes your secret weapon for keeping things juicy while staying low-carb—just make sure they're firm and not too large or they'll be watery.
• Olive oil (1 tablespoon): This small amount prevents sticking and helps the zucchini soften evenly, plus it carries flavor into every corner of your boat.
• Salt and freshly ground black pepper: Never skip the seasoning step—these humble ingredients wake up the zucchini's natural sweetness.
• Sugar-free tomato or pizza sauce (1/2 cup): This is where you prevent hidden carbs from sneaking in; always check labels because some brands hide sugars you don't expect.
• Dried Italian herbs (1 teaspoon): A small pinch goes a long way, especially when the heat brings out these flavors and makes your kitchen smell like an Italian grandmother's kitchen.
• Shredded mozzarella cheese (1 cup): The star of the show—buy it pre-shredded or shred it yourself, but avoid the anti-caking agents by choosing quality when you can.
• Pepperoni slices (24, sugar-free if possible): This is the crispy, salty element that makes people forget they're eating vegetables, so don't skimp on quality here.
• Grated Parmesan cheese (1/4 cup): This adds a sharp, salty edge that balances the richness of the mozzarella and creates those golden, crunchy bits.
• Fresh basil (2 tablespoons, optional): A finish of fresh basil transforms these from dinner into something that feels slightly fancy, even though you made it on a Tuesday.

Instructions

Heat your oven and prep your workspace:

Get the oven to 400°F and line your baking sheet with parchment paper—this small step saves you from scrubbing cheese off the pan later. Having everything ready before you touch the zucchini keeps you from getting frustrated mid-project.

Create your boats:

Wash and slice each zucchini lengthwise, then use a spoon to gently scoop out the center seeds, leaving about a quarter-inch of wall so your boat doesn't fall apart in the oven. You'll feel a little resistance when the spoon hits the flesh—that's perfect, it means you're leaving enough structure.

Season and oil:

Brush the cut sides with olive oil and sprinkle generously with salt and pepper, letting the seasonings settle into the grooves. This step is where the real flavor begins, so don't rush it.

Arrange on the sheet:

Place all your zucchini halves cut-side up in a single layer, making sure they're not touching each other so the heat can circulate and cook them evenly. Crowding the pan is the enemy here.

Add sauce and herbs:

Spoon about 2 tablespoons of tomato sauce into each boat, then sprinkle the Italian herbs over top, which releases their fragrance as they warm up. This is when your kitchen starts smelling like something special.

Layer on the toppings:

Scatter mozzarella first, then arrange 3 pepperoni slices (or more if you're feeling generous), then top with Parmesan so it can crisp up and get golden. The layering matters because it creates different textures in every bite.

Bake until bubbly:

Slide into the oven for 18 to 20 minutes—you're watching for the cheese to turn golden and bubble at the edges, and the zucchini to turn tender when you poke it with a fork. The smell will tell you when you're close, filling your kitchen with pepperoni and melted cheese.

Finish and serve:

Pull them out, add a sprinkle of fresh basil if you have it, and let them cool for just a minute so the cheese sets enough to handle without burning your mouth. Serve warm while everything is still melting together.

My mom came over last Thursday while these were baking and just stood there inhaling the aroma like it was the most complicated French pastry. When I told her they were basically just zucchini and cheese, she rolled her eyes, but after she tasted one she asked for the recipe and has already made them twice. Those are the moments when food becomes about more than nutrition—it becomes a way of telling someone you're thinking about them.

When to Make These

These boats shine brightest during summer when zucchini is abundant and your garden (or farmers market) practically forces them into your hands. But honestly, I make them year-round because they're so quick and satisfy that pizza craving without the heaviness that sometimes makes you regret your dinner choices. They work equally well for a casual family meal or when you're trying to impress someone with the fact that you're eating intentionally without making a big deal about it.

How to Customize Your Boats

The beauty of this recipe is that it's a framework, not a rulebook—I've added everything from caramelized onions to crispy bacon to roasted red peppers depending on what's in my fridge. The key is not to overload them, because too many toppings will make them hard to eat and might prevent the zucchini from cooking through evenly. Keep the total toppings to about the amount of cheese you're already using, and you'll always end up with something delicious.

Storage and Serving

These keep beautifully in the fridge for about three days, and you can reheat them in a 350°F oven until they're warm again—they won't have quite the same cheese texture, but they'll still taste incredible and make great leftovers for lunch. I've also frozen them before baking and just added a few extra minutes to the cooking time when I pulled them straight from the freezer, which is perfect for meal prepping.

• Pair them with a crisp green salad to feel virtuous and add volume without carbs.
• Serve them with a garlic aioli on the side if you're feeling decadent—keto doesn't have to be boring.
• Leftovers are surprisingly good cold, straight from the fridge, if you're the type who eats dessert for breakfast.

Pin It

These zucchini boats remind me that eating well doesn't mean deprivation or settling for something boring—it just means paying attention to what you're putting together. Once you make these once, you'll understand why they've become my go-to solution for busy nights when I want something that tastes intentional and delicious.
