What Ingredients are in Sizzling Flank Steak Fajita Chili?
This flavorful chili combines the best of two beloved dishes—sizzling fajitas and hearty chili—into one satisfying pot of goodness. The star of the show is tender flank steak, which brings a substantial meatiness that you just don’t get with ground beef. Combined with the colorful bell pepper trio and two types of beans, this chili has that perfect balance of protein, vegetables, and fiber that makes for a complete meal in a bowl.
- 1 pound flank steak, cut across the grain into thin strips
- 2 tablespoons vegetable oil
- 1 red bell pepper, chopped
- 1 green bell pepper, chopped
- 1 yellow bell pepper, chopped
- 2 onions, chopped
- 2 cups water
- 3 (15-ounce) cans tomato sauce
- 1 (15-ounce) can ranch style beans
- 1 (15-ounce) can black beans
- 1 (14.5-ounce) can petite diced tomatoes
- 1/4 cup chopped fresh cilantro
- 3 teaspoons dried ancho chile powder
- 2 teaspoons ground cumin
- 2 teaspoons fresh lime juice
- 1 teaspoon garlic salt
- 1 teaspoon ground black pepper
When shopping for these ingredients, the flank steak quality really matters—look for a piece with good marbling for maximum flavor. Can’t find ancho chile powder? Regular chili powder works in a pinch, though you’ll miss some of that authentic smoky depth. And while the recipe doesn’t specify, don’t forget to drain and rinse your beans before adding them to reduce sodium and improve texture. For an extra flavor boost, I sometimes add a splash of liquid smoke or a teaspoon of smoked paprika, giving that distinctive outdoor-grilled taste that makes fajitas so irresistible.

How to Make this Sizzling Flank Steak Fajita Chili
Making this incredible fajita chili starts with properly preparing the flank steak. Take your 1 pound of flank steak and cut it across the grain into thin 1-inch strips—this cutting technique is essential because it breaks up the long muscle fibers and guarantees tender meat rather than tough, chewy pieces. Trust me, the direction of your knife makes all the difference here.
Heat 2 tablespoons of vegetable oil in a large Dutch oven over medium-high heat, then add those beautiful steak strips. You’ll want to cook them for about 5 minutes, stirring frequently so they brown evenly without burning.
Next, toss in your colorful trio of chopped bell peppers—1 red, 1 green, and 1 yellow—along with 2 chopped onions. Let this aromatic mixture cook for another 5 minutes until the vegetables start to soften and release their sweet flavors. The kitchen smells amazing at this point, with that classic fajita sizzle and aroma filling the air.
A high-quality professional Dutch oven will distribute heat evenly, ensuring your vegetables and meat cook perfectly without hot spots.
Now comes the transformation from fajitas to chili. Pour in 2 cups of water, 3 cans of tomato sauce, 1 can each of ranch style beans and black beans, and 1 can of petite diced tomatoes. Add 1/4 cup of fresh chopped cilantro for brightness, along with your seasonings: 3 teaspoons of ancho chile powder, 2 teaspoons each of ground cumin and fresh lime juice, and 1 teaspoon each of garlic salt and black pepper.
Bring this gorgeous mixture to a boil, then reduce the heat and let it simmer for 30 minutes, allowing all those complex flavors to meld together. The longer it simmers, the more the flavors intensify—sometimes I can’t resist letting it go for 45 minutes if I’ve the time.
When serving, a dollop of sour cream and a sprinkle of cheese make perfect optional garnishes that melt beautifully into the hot chili.
Sizzling Flank Steak Fajita Chili Substitutions and Variations

What to Serve with Sizzling Flank Steak Fajita Chili
Because this hearty flank steak fajita chili packs such a flavorful punch, you’ll want to pair it with complementary sides that can stand up to its bold profile.
I recommend warm cornbread or tortilla chips for dipping into that savory broth. A simple green salad with lime vinaigrette adds a fresh counterpoint, cutting through the richness.
For drinks? A cold Mexican beer or zesty margarita works wonders, though limeade satisfies when you’re keeping things non-alcoholic.
You might also consider cilantro lime rice or elote (Mexican street corn) to round out your fiesta-worthy meal. Talk about comfort food perfection.
