Ingredients You’ll Need
For the Base Components
- 8 ounces Elbow Macaroni – The classic pasta shape with curved tubes that perfectly capture and hold the creamy cheese sauce in every bite while providing the ideal texture that’s sturdy enough to support the hearty ingredients
- 1 pound Beef Steak – Diced into bite-sized pieces; choose tender cuts like sirloin for balanced flavor and value, or ribeye for maximum marbling and richness (flank steak works well if sliced against the grain)
- 1 tablespoon Olive Oil – Provides the cooking medium for searing the steak with high smoke point and neutral flavor that won’t compete with the other ingredients
For the Vegetable Medley
- 1 cup Diced Bell Peppers – Use red, green, or a colorful mix for visual appeal and varied sweetness levels; red peppers offer the most sweetness while green provide slight bitterness for complexity
- 1 cup Diced Onion – Yellow onions work best for balanced sweetness and savory depth; their moisture content breaks down during cooking to contribute body to the sauce
For the Creamy Queso Sauce
- 2 cups Pepper Jack Cheese – Shredded from a block for superior melting quality and smooth texture; the jalapeño-studded cheese provides creamy richness with mild to moderate heat that builds gradually
- 1 cup Whole Milk – Full-fat milk creates the proper consistency and richness for the cheese sauce; the fat content helps emulsify the cheese and prevents graininess or separation
- 1 teaspoon Garlic Powder – Provides savory, aromatic depth without the moisture of fresh garlic that could thin the sauce; distributes evenly throughout for consistent flavor
- 1 teaspoon Onion Powder – Enhances the sautéed onions with concentrated allium flavor and adds umami complexity to the cheese sauce
- Salt and Pepper – To taste for seasoning the steak during cooking and adjusting the final dish; use freshly ground black pepper for maximum flavor and aromatic impact
For Garnish
- Chopped Green Onions – Provides fresh, bright flavor and vibrant color contrast that cuts through the rich, creamy sauce while adding a slight onion bite and visual appeal
Step-by-Step Instructions
Cook the Pasta
Bring a large pot of generously salted water (about 1 tablespoon salt per 4 quarts water) to a rolling boil over high heat. Add the elbow macaroni and cook according to package instructions until al dente, typically 7-8 minutes, stirring occasionally to prevent sticking, then drain thoroughly in a colander and set aside, optionally tossing with a small drizzle of olive oil to prevent clumping.
Sear the Steak
Heat the olive oil in a large skillet over medium-high heat until shimmering but not smoking, about 2 minutes. Add the diced steak in a single layer without crowding (work in batches if necessary), season generously with salt and pepper, and cook without stirring for 2-3 minutes to develop a caramelized crust, then stir occasionally until browned on all sides and cooked to your desired doneness, about 5-7 minutes total for medium, then remove to a plate and set aside.
Sauté the Vegetables
In the same skillet with the flavorful fond (browned bits) from the steak, add the diced bell peppers and onions without adding additional oil. Sauté over medium heat, stirring frequently, for 4-5 minutes until the vegetables are softened, fragrant, and beginning to develop slight caramelization at the edges, which concentrates their natural sugars and enhances overall flavor.
Create the Queso Sauce
Reduce the heat to medium-low to prevent scorching and add the whole milk to the skillet with the vegetables, using a wooden spoon to scrape up any browned bits from the bottom of the pan. Stir in the garlic powder and onion powder, then add the shredded pepper jack cheese gradually in three or four additions, stirring constantly in a figure-eight motion until each addition is completely melted before adding more, creating a smooth, creamy sauce without graininess or oil separation, seasoning with additional salt and pepper as needed.
Combine All Components
Add the cooked steak and drained elbow macaroni to the skillet with the cheese sauce, then gently fold everything together using a large spoon or silicone spatula with broad, sweeping motions. Continue folding until every piece of pasta is thoroughly coated with the creamy queso and the steak pieces and vegetables are evenly distributed throughout, ensuring no dry patches of pasta remain.
Garnish and Serve
Transfer the finished Steak & Pepper Jack Queso Mac to individual serving bowls or a large serving dish, then immediately sprinkle the chopped green onions generously over the top for a fresh, vibrant finish. Serve hot while the cheese sauce is at its creamiest consistency, as it will thicken slightly as it cools.
Recipe Notes & Tips
- Cheese Grating Matters – Always shred pepper jack cheese from a block yourself rather than using pre-shredded varieties, as the anti-caking agents in pre-shredded cheese (typically cellulose or potato starch) prevent smooth melting and can create a grainy, separated sauce.
- Temperature Control – Keep the heat at medium-low when making the cheese sauce, as excessive heat causes the proteins in cheese to separate from the fat, resulting in a greasy, broken sauce rather than smooth, creamy queso.
- Steak Doneness – Remember that the steak will continue cooking slightly when added back to the hot cheese sauce, so consider removing it from the skillet when it’s just shy of your target doneness to prevent overcooking.
- Pasta Water Reserve – Before draining the pasta, reserve ½ cup of the starchy cooking water; if your cheese sauce becomes too thick, add this liquid tablespoon by tablespoon to adjust consistency while enhancing creaminess.
- Prevent Pasta Clumping – If preparing components ahead, toss the drained pasta with 1-2 teaspoons of olive oil or butter immediately after draining to create a coating that prevents the noodles from sticking together during storage.
- Batch Cooking Steak – Avoid overcrowding the skillet when searing steak, as this drops the pan temperature and causes steaming rather than browning; cook in two batches if necessary to maintain proper searing temperature.

Storage & Serving Tips
- Refrigerator Storage – Transfer completely cooled leftovers to airtight containers and refrigerate for up to 3 days; the flavors will deepen and meld overnight, often tasting even better the next day.
- Freezing Instructions – Portion into freezer-safe containers or heavy-duty freezer bags, removing as much air as possible, and freeze for up to 2 months; freeze in individual portions for convenient single-serving reheating.
- Reheating Method – For best results, reheat refrigerated portions in a skillet over medium-low heat with 2-3 tablespoons of milk to restore creaminess, stirring frequently; microwave reheating works but may dry out the pasta slightly (add milk to compensate).
- Thawing Frozen Portions – Thaw overnight in the refrigerator for food safety and even reheating; avoid thawing at room temperature, which can promote bacterial growth in the dairy-based sauce.
Creative Variations to Try
- Cajun-Spiced Version – Add 1-2 tablespoons Cajun seasoning to the steak before cooking and incorporate diced tomatoes with green chiles into the sauce for a Louisiana-inspired twist with bold, complex flavors.
- Southwestern Style – Replace bell peppers with poblano peppers, add black beans and corn to the mix, and top with crushed tortilla chips, cilantro, and lime wedges for a Tex-Mex interpretation.
- Mushroom Lovers’ Addition – Sauté 8 ounces of sliced mushrooms (cremini or shiitake work beautifully) along with the peppers and onions for earthy umami depth that complements the beef.
- Milder Family-Friendly Option – Substitute regular Monterey Jack cheese for the pepper jack and add ½ teaspoon smoked paprika for subtle flavor without heat, making it perfect for spice-sensitive family members.
Troubleshooting Common Issues
- Cheese Sauce is Grainy or Separated – The heat was too high or the cheese was added too quickly; if this occurs, remove from heat immediately and whisk in 1-2 tablespoons of cold milk to help re-emulsify the sauce.
- Sauce is Too Thick – Not enough liquid was used or the pasta absorbed too much sauce; thin gradually with reserved pasta water, milk, or cream until you achieve the desired creamy consistency.
- Steak is Tough or Overcooked – The meat was cooked at too high a temperature for too long or an inappropriate cut was used; ensure you’re using tender cuts and remove from heat when slightly underdone, as carryover cooking will continue.
- Pasta is Mushy – The macaroni was overcooked or continued cooking in the hot sauce; always cook pasta to al dente (slightly firm to bite) as it will soften further when combined with the hot cheese sauce.
Why This Recipe Works
The success of this Steak & Pepper Jack Queso Mac lies in the layered development of flavors and the careful construction of a stable cheese sauce. The initial searing of the steak over high heat triggers the Maillard reaction, creating hundreds of complex flavor compounds through the browning of proteins and sugars that form a flavorful fond on the pan bottom. This fond is then dissolved into the sauce through deglazing with milk, incorporating those concentrated flavors throughout the entire dish. The pepper jack cheese melts smoothly when added gradually to warm (not hot) milk because the gradual temperature increase allows the cheese proteins to relax and incorporate into the liquid without seizing or separating. Whole milk provides sufficient fat content to create an emulsion with the cheese, preventing the dreaded grainy or oily texture that results from improper technique. The starch from the pasta also contributes to the sauce’s body, absorbing some liquid while releasing its own starches that help bind everything together. The combination of garlic and onion powders enhances the fresh aromatics from the sautéed vegetables, creating flavor depth without adding moisture that would thin the sauce. At approximately 580-620 calories per serving, this dish provides substantial protein (around 35g), complex carbohydrates for energy, and enough fat to create lasting satiation, making it a complete meal that will keep you satisfied for hours.
