Cook the linguine: Bring a pot of salted water to a boil and cook pasta until al dente. Reserve ½ cup of pasta water and drain the rest.
Prepare the chicken: Season thin-sliced chicken breasts with salt, pepper, and a pinch of smoked paprika. Sear them in a large skillet with a tablespoon of butter until golden brown and cooked through. Remove and set aside.
Make the cowboy butter sauce: In the same skillet, melt remaining butter. Add minced garlic, Dijon mustard, lemon juice, smoked paprika, and red pepper flakes. Stir for about 1 minute until fragrant.
Combine and toss: Add the cooked linguine, chicken, and reserved pasta water. Toss until the pasta is coated in the buttery sauce. For a creamier version, pour in the heavy cream at this stage and stir until smooth.
Finish and serve: Sprinkle with chopped parsley and grated Parmesan. Serve immediately with lemon wedges on the side.
Notes
Tips for the Best Cowboy Butter Chicken Linguine
Don’t overcook the chicken. Thin slices cook fast, so keep an eye on them.
Use fresh lemon juice. Bottled juice dulls the flavor.
Add pasta water gradually. It helps emulsify the sauce for that restaurant-style texture.
Adjust heat to taste. Want more spice? Add extra red pepper flakes or a dash of cayenne.
Common Mistakes to Avoid
Using cold butter: It won’t blend smoothly. Always start with room temperature butter.
Skipping the mustard: It’s the secret tang that balances the richness.
Overcooking the pasta: Slightly firm pasta absorbs the sauce better.
Variations and Substitutions
Protein Swap: Try shrimp, steak strips, or even tofu instead of chicken.
Add veggies: Toss in sautéed spinach, sun-dried tomatoes, or roasted corn for texture.
Dairy-Free: Substitute vegan butter and coconut cream.
Low-Carb: Use zucchini noodles or spaghetti squash instead of linguine.
