What You’ll Need
- 250g (8oz) Linguine Pasta (Dry): We’re using linguine for its classic shape and ability to hold onto the rich sauce. Look for a high-quality pasta made with durum wheat semolina for the best texture.
- 300g (10.5oz) Beef Steak (Sirloin or Flank), Cut into Bite-Size Pieces: Sirloin or flank steak work beautifully here. Flank steak is more affordable, but sirloin offers a slightly more tender bite. Cutting it into bite-sized pieces ensures it cooks quickly and evenly.
- 150g (5oz) Fresh Spinach Leaves: Fresh spinach provides a lovely earthy flavor and vibrant color. Baby spinach is a great option as it’s tender and requires minimal cooking.
- 90g (6 Tbsp) Unsalted Butter, Divided (60g for Sauce, 30g for Red-Pepper Butter): Unsalted butter allows you to control the saltiness of the dish. We’re dividing it to create both a flavorful sauce base and a vibrant red-pepper butter.
- 2 Tbsp (30ml) Olive Oil, Divided: We’re using olive oil for sautรฉing and searing. Extra virgin olive oil adds a lovely fruity note, but regular olive oil works well too.
- 2 Cloves Garlic, Minced: Freshly minced garlic is essential for a fragrant and flavorful sauce.
- 1 Small Shallot, Finely Chopped: Shallots offer a milder, sweeter flavor than onions, adding depth to the sauce.
- 100g (3.5oz) Roasted Red Pepper, Chopped: Roasted red peppers provide a sweet, smoky flavor that’s central to the cowboy butter. You can roast your own or use jarred roasted red peppers for convenience.
- 1 tsp (5ml) Smoked Paprika: Smoked paprika adds a wonderful smoky depth that complements the roasted red pepper and steak.
- 1 tsp (5ml) Lemon Zest: Lemon zest brightens the flavors and adds a zesty aroma.
- 120ml (ยฝ cup) Heavy Cream: Heavy cream creates a rich and luxurious sauce.
- 50g (ยฝ cup) Grated Parmesan Cheese โ Halal-Certified: Parmesan cheese adds a salty, umami flavor and helps thicken the sauce. Ensure it’s halal-certified if you require it.
- 2 Tbsp (30g) Toasted Pine Nuts: Toasted pine nuts provide a delightful crunch and nutty flavor.
- 1 Tbsp (15ml) Fresh Parsley, Chopped: Fresh parsley adds a pop of color and freshness.
- Salt and Freshly Ground Black Pepper, to Taste: Seasoning is key! Adjust the salt and pepper to your preference.
Substitutions & Variations
Don’t have an ingredient on hand? No problem! Here are a few easy substitutions:
- Steak: You can substitute the steak with chicken thighs or shrimp for a different protein option.
- Spinach: Kale or Swiss chard can be used in place of spinach, though they may require a slightly longer cooking time.
- Linguine: Feel free to use your favorite pasta shape, such as fettuccine or spaghetti.
- Heavy Cream: For a lighter sauce, you can use half-and-half or milk, but the sauce won’t be as rich.
Optional (plan-ahead): If youโre shopping for the week, I put this into a 4-Week Meal Plan + Grocery Lists so dinnerโs already decided before your day gets busy.
Step-by-Step Instructions for Red Pepper Cowboy Butter Linguine
- Cook the Linguine: Bring a large pot of generously salted water to a rolling boil. Add the linguine and cook according to package directions, usually around 9-10 minutes, until al dente โ firm to the bite. Don’t overcook it! Al dente pasta holds the sauce much better. Before draining, reserve about ยฝ cup (120ml) of the pasta water. This starchy water is liquid gold; it helps emulsify the sauce and create a beautiful, glossy coating. Drain the pasta thoroughly.
- Prepare the Red Pepper Butter: In a small saucepan, melt 30g (2 tablespoons) of butter over low heat. Add the chopped roasted red pepper, smoked paprika, and lemon zest. Cooking over low heat prevents the butter from browning. Cook for about 2 minutes, stirring occasionally, to allow the flavors to meld. Remove from heat and carefully blend with an immersion blender until completely smooth. If you don’t have an immersion blender, a regular blender works, but be extremely cautious when blending hot liquids โ vent the lid to prevent pressure buildup. Keep the red pepper butter warm while you prepare the rest of the dish.
- Sear the Steak Bites: Generously season the steak bites with salt and freshly ground black pepper. Don’t be shy with the seasoning; steak needs a good amount of salt to bring out its flavor. Heat 1 tablespoon of olive oil in a large skillet (cast iron is ideal for searing) over medium-high heat until shimmering. Add the steak bites in a single layer (work in batches if necessary to avoid overcrowding the pan). Sear for 2-3 minutes per side, until browned and cooked to your desired level of doneness โ remember they will continue to cook slightly when added back to the sauce. Transfer the seared steak to a plate, cover loosely with foil, and let rest. Resting allows the juices to redistribute, resulting in more tender steak.
- Sautรฉ the Aromatics and Spinach: Add the remaining 1 tablespoon of olive oil and 60g (4 tablespoons) of butter to the same skillet. Reduce the heat to medium. Add the minced garlic and finely chopped shallot and sautรฉ for about 1 minute, until fragrant. Be careful not to burn the garlic, as it will become bitter. Add the fresh spinach leaves and cook, stirring constantly, until just wilted โ this should only take 1-2 minutes.
- Create the Cowboy Butter Sauce: Pour in the heavy cream and bring to a gentle simmer. Avoid boiling the cream, as it can separate. Add the grated Parmesan cheese and stir continuously until the cheese is completely melted and the sauce is smooth. Pour in the prepared red pepper butter and mix well to combine. If the sauce appears too thick, gradually add reserved pasta water, one tablespoon at a time, until it reaches a glossy, coating consistency.
- Combine and Serve: Add the drained linguine to the skillet with the sauce and toss thoroughly to coat every strand evenly. Return the seared steak bites to the pan and gently mix them in, being careful not to overcook or break the meat.
- Plate and Garnish: Plate the pasta in shallow bowls. Use a fork to twirl a nest of linguine, then spoon a small pool of extra red-pepper butter around the edge for a beautiful presentation. Sprinkle generously with toasted pine nuts and chopped fresh parsley for added texture, flavor, and visual appeal. Serve immediately.
Why This Red Pepper Cowboy Butter Works
The magic of this dish lies in the Cowboy Butter โ a blend of softened butter, roasted red peppers, smoked paprika, and lemon zest. The roasting of the red pepper deepens its sweetness and adds a smoky undertone that complements the steak beautifully. Smoked paprika enhances this smokiness, while the lemon zest provides a bright, acidic counterpoint to the richness of the butter and cream. The pasta water is crucial; its starchiness helps bind the sauce, creating a luxurious, velvety texture that clings to the linguine.
Steak Selection and Preparation Tips
Choosing the right cut of steak is key. Sirloin and flank steak are excellent choices for this recipe because they are relatively lean and cook quickly. Flank steak benefits from being sliced against the grain after cooking to maximize tenderness. For best results, pat the steak bites dry with paper towels before seasoning. This helps them sear properly and develop a beautiful crust. Don’t overcrowd the pan when searing; work in batches if necessary.

Roasting Your Own Red Peppers
While store-bought roasted red peppers are convenient, roasting your own elevates the flavor significantly. To roast red peppers, place them directly over a gas flame or under a broiler, turning occasionally, until the skin is blackened and blistered on all sides. Place the roasted peppers in a bowl and cover with plastic wrap for 10-15 minutes to steam. This makes it easier to peel off the skin. Once peeled, seeded, and chopped, the roasted red peppers are ready to use in the Cowboy Butter.
Variations and Additions
Feel free to customize this dish to your liking! A pinch of red pepper flakes can add a touch of heat. Sun-dried tomatoes would complement the roasted red pepper flavor. You could also add other vegetables, such as mushrooms or bell peppers, to the skillet along with the spinach. For a spicier kick, consider using a spicy Italian sausage instead of steak.
Frequently Asked Questions (FAQ)
- Can I use a different type of pasta? Yes, fettuccine or spaghetti would also work well.
- Can I make the red pepper butter ahead of time? Absolutely! You can make it up to 3 days in advance and store it in the refrigerator. Reheat gently before using.
- Is this dish gluten-free? No, linguine contains gluten. However, you can easily make it gluten-free by using gluten-free pasta.
