Instructions

Step 1

Preheat your oven to 400°F (200°C). This temperature is ideal for quickly roasting the chicken and vegetables while allowing the cottage cheese to melt into a creamy, cohesive sauce without curdling. While the oven heats, prepare your ingredients: thinly slice the onion and bell peppers into strips about 1/4-inch thick. Uniform slicing ensures even cooking and a pleasant texture. Mince the garlic cloves finely so they distribute evenly. Cut the chicken breasts into thin strips, about 1/2-inch wide, against the grain for tenderness. Pat the chicken dry with paper towels to remove excess moisture, which helps achieve better browning during the stovetop sear.

Step 2

Heat the olive oil in a large oven-safe skillet or cast-iron pan over medium-high heat. Once the oil shimmers (about 30 seconds), add the chicken strips in a single layer. Do not overcrowd the pan; if necessary, cook in batches to ensure a golden sear rather than steaming. Let the chicken cook undisturbed for 2-3 minutes until the bottom is deeply browned. Flip the strips and cook another 2 minutes. The goal is a flavorful crust from the Maillard reaction, which adds depth to the final dish. Remove the chicken to a plate and set aside.

Step 3

In the same skillet, add the sliced onion and bell peppers. There should be enough residual oil and browned bits (fond) to flavor the vegetables. Sauté over medium-high heat, stirring occasionally, for 4-5 minutes until the vegetables begin to soften and develop char marks. The onions should become translucent and slightly caramelized, while the peppers retain some crunch. Add the minced garlic and cook for 30 seconds until fragrant, stirring constantly to prevent burning.

Step 4

Sprinkle the fajita seasoning over the vegetables and stir to coat evenly. The spices will bloom in the heat, releasing their aromas. Pour in the chicken broth and use a wooden spoon to scrape up any browned bits from the bottom of the pan. This deglazing step incorporates all the savory flavors into the sauce. Let the broth simmer for 1-2 minutes until slightly reduced.

Step 5

Return the seared chicken strips to the skillet along with any accumulated juices. Stir everything together to combine. Remove the skillet from the heat. Dollop the cottage cheese evenly over the top of the chicken and vegetable mixture. Do not stir it in yet; the cottage cheese will melt and spread during baking, creating pockets of creamy richness. If using, sprinkle the shredded Mexican blend cheese over the top for an extra cheesy crust.

Step 6

Transfer the skillet to the preheated oven and bake for 12-15 minutes, or until the cottage cheese is melted and bubbly, and the chicken is cooked through (internal temperature of 165°F/74°C). The edges should be lightly golden. Remove from the oven and let rest for 2 minutes. Garnish with fresh cilantro or parsley and serve with lime wedges if desired. The cottage cheese will have transformed into a luscious, creamy sauce that clings to the chicken and vegetables.

For best results

  • For the best texture, choose low-fat cottage cheese with 2% milkfat. Full-fat cottage cheese can be used but will increase the calorie and fat content, while nonfat may result in a thinner sauce. Small-curd cottage cheese blends more smoothly, but large-curd also works if you prefer a chunkier texture. If you want an ultra-creamy sauce, you can blitz the cottage cheese in a food processor for 30 seconds before adding it to the dish.
  • To make your own fajita seasoning, combine 1 tablespoon chili powder, 1 teaspoon smoked paprika, 1 teaspoon cumin, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon oregano, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. This homemade blend is lower in sodium and free of anti-caking agents. Store any extra in an airtight container for up to 3 months.
  • If you don't have an oven-safe skillet, transfer the chicken and vegetable mixture to a greased 9×13-inch baking dish before adding the cottage cheese and baking. The baking time remains the same. For extra browning, you can broil the dish for the last 2 minutes, watching carefully to avoid burning.
  • For meal prep, divide the cooled fajita bake into individual airtight containers. It will keep in the refrigerator for up to 4 days. Reheat in the microwave for 1-2 minutes or in a 350°F oven for 10 minutes. The cottage cheese sauce may thicken upon refrigeration, so add a splash of chicken broth or water when reheating to restore the creamy consistency.
  • To reduce sodium, use low-sodium chicken broth and make your own fajita seasoning. Also, choose cottage cheese with no added salt. You can further control sodium by not adding extra salt until the end, after tasting. The natural flavors from the spices and vegetables are quite robust.

Variations

  • For a vegetarian version, replace the chicken with 1 can (15 oz) of drained and rinsed black beans or 2 cups of sliced portobello mushrooms. Sauté the mushrooms until they release their moisture and brown. The cottage cheese provides ample protein, making this a satisfying meatless meal.
  • To make it dairy-free, substitute the cottage cheese with 1 cup (240g) of blended silken tofu (drained) mixed with 1 tablespoon nutritional yeast for a cheesy flavor. Use a dairy-free shredded cheese alternative on top. The texture will be slightly different but still creamy and delicious.
  • For a low-carb/keto version, omit the bell peppers (or use only a small amount) and add more vegetables like zucchini or cauliflower. Replace the onion with a smaller amount of shallots. Ensure your fajita seasoning has no added sugar. Serve over cauliflower rice or a bed of greens.
  • Add more heat by including a diced jalapeño or serrano pepper when sautéing the vegetables. You can also stir in 1/2 teaspoon of cayenne pepper or chipotle powder with the fajita seasoning. For a smoky twist, use chipotle peppers in adobo sauce – mince one pepper and add with the garlic.
  • Swap the protein: use boneless skinless chicken thighs for a juicier result, or try lean ground turkey or beef. If using ground meat, brown it first, then remove and proceed with the vegetables. Shredded rotisserie chicken is a great shortcut – simply skip the searing step and add the chicken with the broth.

Common Questions

Can I use Greek yogurt instead of cottage cheese?
Yes, plain Greek yogurt can be substituted for cottage cheese. Use the same amount (1 cup) and stir it in at the end before baking. However, Greek yogurt has a tangier flavor and may separate if overbaked, so reduce the baking time by 2-3 minutes and check for doneness earlier. Cottage cheese is recommended for its mild flavor and creamy, meltable texture.
How do I prevent the cottage cheese from becoming watery?
Cottage cheese can release whey when heated, but this is normal and usually reabsorbs as it bakes. To minimize excess liquid, choose a thicker cottage cheese (small-curd or dry-curd) and avoid stirring it into the dish before baking – let it melt on top. Also, ensure your chicken and vegetables are not overly wet; pat them dry before cooking.
Can I freeze this chicken fajita bake?
Yes, this dish freezes well. Allow it to cool completely, then transfer to a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the refrigerator and reheat in a 350°F oven until warmed through (about 20 minutes). The cottage cheese sauce may become slightly grainy after freezing, but stirring in a little broth or milk can help restore the texture.
What can I serve with this fajita bake?
This dish is quite filling on its own, but you can serve it with warm tortillas (corn or flour), over a bed of rice or quinoa, with a side of black beans, or on a fresh green salad. For a low-carb option, try cauliflower rice or lettuce wraps. A dollop of sour cream or avocado slices also complements the flavors beautifully.
How do I know when the chicken is fully cooked?
The safest way is to use an instant-read thermometer inserted into the thickest piece of chicken. It should read 165°F (74°C). If you don’t have a thermometer, cut into a piece of chicken; the juices should run clear and the meat should be opaque throughout with no pinkness. Since the chicken is cut into thin strips, it cooks quickly.
Can I make this dish ahead of time?
Absolutely! You can assemble the entire dish (without baking) up to 24 hours in advance. Cover and refrigerate. When ready to bake, you may need to add 5-10 minutes to the baking time since the dish starts cold. Alternatively, bake it fully, then reheat portions as needed. This makes it ideal for meal prep.
