What Goes Into This Recipe – Ingredients
- 2 medium zucchini, ends trimmed
- 2 medium yellow squash, ends trimmed (optional, but great for color and sweetness)
- 2 tablespoons avocado oil (or light olive oil)
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon smoked paprika (or regular paprika)
- 1/4 teaspoon onion powder
- Optional: 1/4 cup finely grated Parmesan for extra crunch
- Optional finish: Pinch of red pepper flakes or a squeeze of lemon
Instructions
- Preheat like you mean it: Set the oven to 225–250°F (low and slow dries them out) or preheat the air fryer to 300°F.
Line baking sheets with parchment or silicone mats.
- Slice consistently: Use a mandoline for 1/16–1/8-inch slices. Thinner = crispier. Uniform thickness prevents half-burnt, half-soggy drama.
- Draw out moisture: Lay slices on paper towels, sprinkle lightly with salt, and let them sweat for 10–15 minutes.
Pat dry thoroughly. This step is the difference between chips and mush, FYI.
- Season smart: Toss slices with avocado oil, salt, pepper, garlic powder, paprika, and onion powder in a large bowl. If using Parmesan, add it now and toss lightly.
- Pan placement: Arrange slices in a single layer—no overlapping.
Crowding equals steaming equals sadness.
- Bake or air fry:
- Oven: Bake 60–90 minutes, flipping halfway, until edges are browned and centers are dry. Rotate pans if needed. Keep an eye on the last 15 minutes.
- Air fryer: Cook in batches at 300°F for 12–18 minutes, flipping at the 8–10 minute mark.
Lower temp if they brown too fast.
- Final crisp: Once golden and dry, kill the heat and let them sit in the warm oven for 10 minutes with the door slightly cracked. Extra insurance for crunch.
- Finish + taste: Sprinkle a pinch more salt while warm. Add red pepper flakes or lemon if you’re fancy.
- Cool completely: Transfer to a rack to cool.
Chips crisp further as they cool, so don’t judge too early.
How to Store
- Cool 100% before storing. Any residual heat equals trapped steam equals limp chips.
- Use a paper towel-lined airtight container at room temp for up to 3 days. Add a fresh paper towel on top to absorb moisture.
- Refresh if needed: Pop in a 250°F oven for 5–8 minutes to re-crisp. Let cool before eating.
- Avoid the fridge. Refrigeration invites moisture and ruins texture, IMO.
Nutritional Perks
- Keto-friendly: Zucchini and yellow squash are low in net carbs, so you get the crunch without the carb crash.
- Micronutrient boost: Rich in vitamin C, potassium, and antioxidants like lutein—great for skin, eyes, and recovery.
- Healthy fats: Avocado oil adds monounsaturated fats that keep you satisfied and support heart health.
- Calorie-conscious: Even with oil and Parmesan, these are lighter than fried chips.
Portion control still matters, but the math is on your side.
Pitfalls to Watch Out For
- Skipping the sweat: If you don’t salt and blot the slices first, you’ll get soggy disappointment, not chips.
- Inconsistent slices: Thicker slices take longer and may never dry fully. Mandoline > knife here.
- Too hot, too fast: High heat browns the edges while the centers stay soft. Keep it low and patient.
- Crowded pans: Overlapping causes steaming.
Give each slice personal space like it pays rent.
- Over-salting early: Remember the sweat step adds salt. Season lightly at first; adjust after baking.
Alternatives
- Different seasonings:
- Ranch blend + dill
- Chili-lime + Tajín + lime zest
- Everything bagel seasoning
- Parmesan + garlic + parsley
- Cajun spice for a kick
- Coating tweaks: Add 1 tablespoon almond flour per pound of squash for extra crunch; shake off excess before baking.
- Oil options: Ghee or light olive oil work. Avoid extra virgin at high temps—can taste bitter.
- Veggie swaps: Try thin-sliced eggplant, daikon, or turnips.
Keep the same low-temp drying strategy.
- Dipping ideas: Garlic aioli, spicy mayo, keto ranch, or a lemon-herb yogurt dip. Zero shame in being a dip person.
FAQ
How do I get them super crispy without burning?
Low temperature, consistent slices, and a moisture-removal step are the holy trinity. Bake at 225–250°F, flip halfway, and let them finish drying in the warm oven.
If edges darken too fast, lower the temp and extend the time.
Can I use only zucchini or only yellow squash?
Yes. Zucchini is slightly more neutral; yellow squash can be a touch sweeter. Using both gives great flavor and color contrast, but either works perfectly.
Do I need a mandoline?
You’ll get the best results with one because uniform thickness equals uniform crisp.
A sharp knife can work, but aim for very thin, consistent slices. Consider freezing the squash for 15 minutes before slicing to steady it.
Are these chips actually keto?
Absolutely. Squash is naturally low in net carbs, and the oil and optional Parmesan add fat without carbs.
Just watch the portion if you’re strict tracking—yes, even “healthy” chips add up.
Why are my chips still soft after baking?
They likely needed more time or better moisture removal. Try a longer bake at low heat, then a 10-minute rest in the warm oven. Cooling on a rack helps them crisp fully.
Can I make them ahead for a party?
Yes—make them the day before, store with paper towels in an airtight container, and refresh in the oven for a few minutes before serving.
They’ll taste freshly made with minimal effort.
What’s the best dip for these?
Keto ranch is classic. For flair, mix Greek yogurt (or mayo), lemon zest, garlic, and dill. Spicy mayo with a dash of sriracha is elite, IMO.
