Tips for success

To enhance the smoky profile of the dish, add a small teaspoon of chipotle powder or a splash of liquid smoke to the slow cooker at the beginning. This adds an extra layer of depth that pairs beautifully with the steak and queso. If you enjoy extra heat, feel free to add fresh diced serrano peppers along with the jalapeños during the final serving stage.

If you find the sauce is too thick after adding the pasta, add a small amount of reserved pasta water or warm beef broth to reach your desired consistency. Stir gently to avoid breaking the penne noodles.

Adding the fresh cilantro and pico de gallo just before serving ensures that the herbs remain crisp and vibrant, providing a necessary contrast to the rich, heavy sauce.

Variations

Chicken Fajita Pasta: Substitute the flank steak with cubed chicken breast. Ensure the chicken reaches an internal temperature of 165°F (74°C) during the slow cooking process to ensure it is fully cooked and safe to eat.
Vegetarian Fajita Pasta: Replace the flank steak with extra sliced bell peppers, zucchini, and black beans. Use vegetable broth instead of beef broth to keep the flavor profile light and savory while maintaining the creamy texture.

Storage and make-ahead

Fridge: Store in an airtight container for up to 3 days.
Freezer: Not recommended, as the creamy cheese sauce may separate upon thawing.
Reheat: Reheat on the stovetop over low heat, adding a splash of broth to restore the sauce's creaminess.

Transfer any leftovers to an airtight container within two hours of cooking. Store in the refrigerator for up to three days. When reheating, add a tablespoon of water or broth to the container to prevent the pasta from drying out, as the cheese sauce tends to thicken significantly once chilled.

You can prepare the vegetables and slice the steak up to 24 hours in advance, storing them in separate containers in the refrigerator.

The pasta can also be cooked ahead of time; rinse it with cold water and toss it with a little oil to prevent sticking before storing. This allows you to assemble and start the slow cooker with minimal effort when you are ready to cook.

Serving ideas

Serve this creamy pasta in wide, shallow bowls to showcase the beautiful colors of the peppers, steak, and vibrant garnishes.

Providing extra lime wedges on the side allows guests to add a burst of acidity, which cuts through the richness of the queso and enhances the Tex-Mex flavors. A side of warm flour tortillas or a crisp green salad with a lime vinaigrette makes for a complete, well-rounded dinner.

For a formal presentation, garnish each serving with an extra sprinkle of cilantro and a few thinly sliced jalapeños. Ensure the pasta is served piping hot so that the cheese sauce maintains its ideal, pourable consistency.

If you have guests with different heat preferences, serve the sliced jalapeños on the side so everyone can customize their own spice level.

Frequently asked questions

Can this be made ahead of time?

Yes, you can prep the ingredients, such as slicing the steak and vegetables, up to 24 hours in advance. Keep them in the refrigerator until you are ready to assemble the slow cooker. The pasta should be cooked just before serving to ensure the best texture.

Why does the sauce separate?

Sauce separation often occurs if the slow cooker is set to a high temperature, causing the cheese to overheat. Always cook on the low setting and stir the cheese in gradually at the very end to ensure a smooth, emulsified sauce.

Is it possible to use different pasta shapes?

Absolutely. While penne is recommended for its ability to hold the sauce, you can use other sturdy shapes like rigatoni or rotini. Avoid delicate or long, thin noodles like angel hair, as they may become mushy when folded into the thick queso sauce.

Creamy Crockpot Steak Fajita Queso Pasta

Prep 15 minCook 3 h 30 minRest 5 minTotal 3 h 50 minServes 6

Ingredients

2 lb flank steak, cut into strips
3 bell peppers, sliced
1 red onion, sliced
2 tbsp fajita seasoning
10 oz Rotel tomatoes
2 cups beef broth
8 oz cream cheese
2 cups Pepper Jack cheese, shredded
16 oz penne pasta, cooked
1/2 cup pico de gallo, jalapeños, cilantro, for serving

Instructions

Place the flank steak strips, sliced bell peppers, and sliced red onion into the slow cooker. Sprinkle the fajita seasoning over the ingredients, then add the Rotel tomatoes and beef broth. Ensure the steak is evenly distributed among the vegetables for consistent cooking.
Cover the slow cooker with the lid and set it to cook on LOW for 3.5 hours. During this time, the steak will braise in the flavorful broth, becoming tender and infused with the fajita spices. Ensure the steak reaches an internal temperature of at least 145°F (63°C) and let the meat rest for at least 3 minutes before proceeding.
Once the steak is tender, stir in the cream cheese and shredded Pepper Jack until the sauce is smooth and creamy. Fold in the cooked penne pasta and heat until warmed through. Serve immediately, topped with fresh pico de gallo, sliced jalapeños, and chopped cilantro for a vibrant finish.
