Why This Recipe Works

This breakfast skillet succeeds because it layers complementary flavors and textures in a logical sequence.

The final touch of melted cheese creates a richness that ties all components into one cohesive, restaurant-quality dish. 

Why you’ll love this recipe

It only takes one time to fall in love with a breakfast skillet recipe like this. The ingredients are easy to find at your local supermarket and typically quite affordable, making it an excellent choice for home cooks who value simplicity and budget-friendliness.

Customizing it with additional toppings, different proteins, and other changes is straightforward. 

Ingredients

For the Chicken:

• Boneless skinless chicken breast – Provides lean protein that takes on fajita flavors beautifully when properly seasoned
• Fajita seasoning blend – Creates authentic Tex-Mex flavor with its combination of chili powder, cumin, paprika, and other spices

For the Vegetables:

• White onion – Adds sweetness and aromatic foundation when sautéed until tender
• Bell pepper – Provides crunch, color, and subtle sweetness that complements the seasoned chicken
• Vegetable oil – Used for cooking chicken and vegetables to golden perfection

For the Base:

• Boiled potatoes or frozen hash browns – Create the crispy, satisfying foundation that makes this dish so filling
• Large eggs – Provides additional protein and creamy texture that binds all components together
• Half and half – Makes eggs extra fluffy and rich when whisked together before cooking

For Finishing:

• Shredded cheddar cheese – Melts beautifully over the hot skillet, adding richness and binding flavors
• Salt and pepper – Essential seasonings that enhance all other flavors in the dish

Ingredient notes

Remember the optional toppings, such as sour cream, guacamole, salsa, and similar choices, to add even more flavor to your skillet.

You can substitute your favorite type of shredded cheese for cheddar, including Mexican/Jack blends or other varieties. You can also choose whichever color of bell pepper you’d like, with green ones lending a freshness and crunch while red, yellow, and orange varieties add a subtle sweetness.  

How to make Denny’s Chicken Fajita Breakfast Skillet

While the final result may be impressive, the techniques required to cook this skillet are straightforward enough for any home cook to handle:

1. Rub chicken breast with the fajita seasoning and let it sit for 30 minutes to marinate. 
2. Heat a skillet over medium heat and add the chicken. Cook until it reaches an internal temperature of 165 degrees Fahrenheit, flipping to ensure all sides are browned. Remove the chicken and set aside.
3. Turn the heat to high, then add the chopped onion and bell pepper to the skillet. Cook until softened. Remove from the skillet and set them aside.
4. Heat vegetable oil in the skillet, then add potatoes or hashbrowns. Cook until browned and crispy, then split in half and add to serving plates/bowls.
5. Whisk the eggs and half and half, then season with salt and pepper. Use this mixture to make two small omelets (one for each plate) or a single large one split in half for each serving.

6. Plate the omelet onto the potatoes, then top it with sliced chicken breast strips, peppers, onions, and shredded cheese.
7. Add any toppings like salsa, guacamole, or sour cream, and then dig in!

What to serve with a Chicken Fajita Breakfast Skillet 

One of the best advantages of this hearty skillet is that it includes nearly an entire breakfast in one dish. However, it’s easy to supplement with sides like fresh fruit or additional breakfast meats such as bacon and sausage.

You can add your favorite toast, croissant, biscuit, or roll, ideally with quality butter, jam, or jelly. Wash it all with a cup of steaming hot coffee or tea or refreshing milk or juice.

Storage & Reheating Instructions

• Freezing Notes: Not recommended for freezing due to texture changes in eggs and potatoes upon thawing. Fresh preparation yields much better results
• Refrigerator Storage: Store cooled leftovers in airtight containers for up to 3 days for best quality and safety
• Reheating Methods: Reheat in a 350°F oven in an oven-safe dish until heated through, about 10-15 minutes. For quicker reheating, use short microwave bursts, stirring between intervals to ensure even heating
