Ingredients You'll Need
Chicken breasts: Go for 1 ¼ lb (about 2 medium). Thin-cutlets cook evenly; if your grocery only sells thick pieces, slice them horizontally or pound them to ¾ inch.
Zucchini: Three medium zucchini (around 1 ½ lb) yield enough “noodles” for four hungry eaters. Look for glossy, firm skins and no soft spots. Yellow squash works too, but zucchini holds less water.
Shredded mozzarella: Part-skim melts creamily without excess grease. For an extra flavor punch, substitute 30% with sharp provolone.
Freshly grated Parmesan: Pre-shredded tub cheese contains anti-caking agents that can turn grainy under heat. Buy a block and grate it yourself; you’ll taste the difference.
Garlic: Three cloves, minced. In a hurry? Freeze-dried garlic plus a drizzle of olive oil rehydrates in seconds.
Crushed red-pepper flakes: Optional, but the gentle heat balances the richness of the cheese. Reduce to ⅛ tsp if serving spice-sensitive palates.
Olive oil & butter combo: Butter browns the chicken; olive oil raises the smoke point so the dairy solids don’t burn.
Italian seasoning: A no-fuss blend of oregano, basil, thyme. Make your own: 1 tsp each dried oregano and basil + ½ tsp dried thyme.
Low-sodium chicken broth: Helps deglaze the pan so the browned bits (a.k.a. flavor gold) become your two-minute pan sauce.
Xanthan gum (optional): A pinch thickens the broth into glossy gravy without adding carbs. Skip it if you don’t keep specialty ingredients on hand.
How to Make Cheesy Chicken and Zucchini Stir Fry for a Low Carb Dinner
Prep the produce
Trim zucchini ends. Using a spiralizer or julienne peeler, cut them into ¼-inch-thick “zoodles.” Spread on a clean kitchen towel, sprinkle with ½ tsp kosher salt, and let sit 10 min. The salt draws out moisture—your secret weapon against soggy stir fry. Pat dry.
Season the chicken
Cut breasts into ¾-inch cubes. In a medium bowl toss with 1 tsp kosher salt, ½ tsp black pepper, 1 tsp Italian seasoning, and ¼ tsp paprika for color.
Heat the skillet
Place a 12-inch stainless or cast-iron skillet over medium-high heat. Add 1 Tbsp olive oil plus 1 Tbsp butter; swirl until the butter foams but hasn’t browned.
Sear the chicken
Spread cubes in a single layer; cook 3 min undisturbed. Flip; cook 2 min more. They should be golden with a slight crust. Transfer to a plate. (They’ll finish cooking later.)
Aromatics & deglaze
Lower heat to medium; add remaining 1 Tbsp butter plus minced garlic and ¼ tsp red-pepper flakes. Sauté 30 sec until fragrant. Pour in ½ cup chicken broth; scrape the brown bits with a wooden spoon.
Add zucchini
Increase heat back to medium-high. Add zucchini noodles; toss 2 min until just beginning to soften. They should retain a gentle crunch.
Return chicken
Slide chicken (and any juices) back into the pan. Sprinkle ¼ tsp xanthan gum over everything; stir 30 sec so the sauce lightly thickens and coats the meat and veg.
Cheese it up
Reduce heat to low. Sprinkle 1 cup shredded mozzarella and ¼ cup grated Parmesan evenly across the skillet. Cover with a tight lid 1–2 min until cheese melts into dreamy strings. Serve hot, garnished with chopped parsley or basil.
Expert Tips
Don’t skip the salt-wilt step
Drawing moisture from zucchini beforehand prevents a watery stir fry and keeps the cheese meld luxuriously thick.
Hot pan = no sticking
Let your skillet preheat until the butter foams immediately; this creates a natural non-stick surface for golden chicken.
Make it dairy-light
Swap half the mozzarella for shredded part-skim mozzarella and use nutritional yeast instead of Parmesan for a lower-lactose version.
Double the sauce
Add an extra splash of broth and a pinch more xanthan if you like to spoon the silky sauce over cauliflower rice.
Budget hack
Buy family-size chicken breasts when they’re on sale, cube, and freeze flat on a sheet pan. Transfer to a bag—no clumps, instant portion control.
Crusty cheese edge
For those coveted lacy cheese edges, leave the skillet uncovered the last 30 sec so the cheese that touches the pan crisps.
Variations to Try
- Mediterranean vibe: Swap Italian seasoning for 1 tsp dried oregano + ½ tsp lemon zest; finish with crumbled feta instead of Parmesan.
- Spicy Cajun: Dust chicken with 1 Tbsp Cajun spice and add diced bell pepper; use shredded sharp cheddar for the cheese blend.
- Mushroom lover: Sauté 8 oz sliced cremini with the garlic; deglaze with a splash of dry white wine for depth.
- Bright & herby: Stir in ½ cup halved cherry tomatoes and a handful of spinach during the last 2 min of cooking for color and freshness.
Storage Tips
Refrigerate: Cool leftovers completely, transfer to an airtight container, and refrigerate up to 4 days. The zucchini will release a little liquid; simply reheat in a dry skillet over medium heat until warmed through—the excess moisture evaporates quickly.
Freeze: While zucchini can get soft upon thawing, if you’re in batch-cook mode, portion the fully cooled stir fry into freezer-safe bags, press out air, and freeze up to 2 months. Thaw overnight in the fridge and reheat as above. Note: cheese may appear slightly separated; a brisk stir while reheating brings it back together.
Make-ahead components: Cube and season the chicken up to 24 hrs ahead; store in a zip-top bag. Salt-wilt zucchini and pat dry; refrigerate in a paper-towel-lined container for up to 2 days. At dinnertime, all that’s left is the 10-minute sear-and-melt.
