Keto Chicken Enchilada Zucchini

There's something quietly satisfying about turning zucchini into vessels for dinner. I discovered these boats on a Tuesday when my CSA box arrived overflowing with zucchini—the kind of abundance that makes you either creative or desperate. What started as an experiment in using what I had became one of those dishes I now crave, especially when I want something that feels indulgent but doesn't derail my goals. The cheese bubbles as it bakes, the chicken stays tender, and somehow the whole thing tastes far more special than the modest ingredient list suggests.

I made this for my brother when he visited last summer, skeptical that a zucchini boat could genuinely satisfy someone who'd just come from taco Tuesday at his favorite spot downtown. He went back for seconds and asked for the recipe, which felt like winning an award. That moment taught me something: when you nail the seasoning and don't skip the cheese, people stop thinking about what's missing and start thinking about when they can eat it again.

Ingredients

• Medium zucchini (4): Look for ones that are uniform in size so they cook evenly; too large and the flesh gets watery, too small and you won't have room for filling.
• Red onion (1 small, finely chopped): The brightness cuts through the richness of the cheese and adds a subtle sweetness that rounds out the spices.
• Garlic (2 cloves, minced): Fresh garlic makes all the difference here—bottled just won't give you that aromatic punch.
• Cooked chicken breast (2 cups shredded): Rotisserie chicken from the store saves you time and works beautifully if you're short on hours; just make sure it's unseasoned or lightly seasoned.
• Sugar-free enchilada sauce (1 cup): This is your flavor backbone, so taste your brand first—some are spicier than others.
• Chili powder, ground cumin, smoked paprika (1 tsp, 1/2 tsp, 1/2 tsp respectively): These three working together create that authentic enchilada depth without any heat if you prefer mild.
• Salt and black pepper (1/2 tsp salt, 1/4 tsp pepper): Season to your taste at the end; remember the cheese adds saltiness.
• Shredded Mexican cheese blend (1 1/2 cups): A mix keeps things interesting, but honest cheddar works wonderfully if that's what you have.
• Sour cream (2 tbsp, optional): A dollop at the end adds coolness and tang that balances the baked richness.
• Fresh cilantro, jalapeño, avocado (for garnish): These toppings feel optional until you taste the difference they make.

Instructions

Heat your oven and prep the boats:

Start your oven at 400°F and while it's warming, slice your zucchini lengthwise. Using a spoon, gently scoop out the center flesh, keeping about a quarter-inch wall so your boats hold their shape—this is easier than it sounds once you get the angle right.

Save and chop your scooped zucchini:

Don't throw away what you've scooped; chop about half a cup of it finely and set it aside. This becomes part of your filling and adds moisture and flavor you'd otherwise miss.

Arrange zucchini in the baking dish:

Place your hollowed boats cut-side up in a large baking dish, leaving a little space between them so heat circulates.

Build your filling base:

Heat olive oil in a skillet over medium heat and sauté your chopped red onion for a few minutes until it softens and becomes translucent. You'll notice it smells sweeter as it cooks—that's when you know it's ready.

Add the aromatics and reserved zucchini:

Stir in minced garlic and your chopped zucchini flesh, cooking just until fragrant, about a minute. Don't let the garlic brown.

Combine everything with the chicken:

Add your shredded chicken, enchilada sauce, chili powder, cumin, smoked paprika, salt, and pepper to the skillet. Stir well and let it simmer for three to four minutes so the flavors marry and the mixture heats through.

Fill and top:

Spoon the chicken mixture evenly into each zucchini boat, then scatter your shredded cheese over the top. Don't be shy with the cheese—it's what makes these boats shine.

Bake until tender and bubbly:

Bake for twenty to twenty-five minutes, watching until the zucchini is fork-tender and the cheese is melted and bubbling at the edges. The cheese might brown slightly, which is exactly what you want.

Finish and serve:

Let them cool for a minute so they're easier to handle, then garnish with cilantro, jalapeño slices, and avocado if you're using them. A small spoonful of sour cream on top adds a cool, tangy note that's hard to resist.

Pin It

One evening I made these for a friend who'd just started eating keto, worried they wouldn't feel like enough after years of flour tortillas and all the traditional trimmings. Watching them realize that vegetables could taste this satisfying, that cheese-covered boats could feel celebratory rather than like a compromise—that changed how I think about cooking for people with different goals. Food that honors what someone needs and still tastes like joy is rare.

Why These Boats Win Every Time

The magic lies in the simplicity of the assembly and the depth of flavor you get from such straightforward ingredients. Zucchini is neutral enough to cradle the spiced chicken without competing, and when it bakes it softens into something almost creamy. The cheese isn't just a topping; it melds with the filling and creates pockets of richness. Everything cooks in one vessel, which means less cleanup and more time enjoying the meal.

Make Them Your Own

This recipe is a foundation, not a rulebook. I've made versions with ground turkey when chicken wasn't on hand, swapped the enchilada sauce for salsa verde when I had it, and once added diced green chilies straight into the filling for extra depth. Some nights I pile on the avocado and jalapeño, other nights I keep it simple with just cilantro. The framework stays the same—seasoned protein, vegetables, cheese—but the details bend to what you're craving and what your kitchen holds.

Pairing and Serving Ideas

These boats are substantial enough to stand alone, but they shine when you pair them with something bright and cool. A simple salad with lime vinaigrette, a side of cauliflower rice, or even just a cold glass of sparkling water with lime feels right. If you're cooking for guests, set out the cilantro, jalapeños, and avocado as optional toppings so everyone can customize their plate. Leftovers reheat gently in a 325-degree oven for about ten minutes, and they taste just as good the next day.

• Make a quick cilantro-lime crema by mixing sour cream with lime juice and cilantro to drizzle on top.
• If you have time, roast the zucchini flesh beforehand for a slightly caramelized flavor.
• Double the recipe and freeze the unbaked boats for busy weeknights.
