Bring a large pot of salted water to a rolling boil over high heat. Add pasta and cook according to package directions until al dente, about 8-10 minutes. Reserve 1/4 cup pasta water before draining—this starchy liquid becomes crucial for your sauce later.
While pasta cooks, heat olive oil and 2 tbsp butter in a large skillet over medium heat until shimmering. Add minced garlic and cook for 45-60 seconds until fragrant but not brown, stirring constantly to prevent burning.
Reduce heat to low and add remaining 4 tbsp butter to the skillet with garlic. Stir gently to combine, then add red pepper flakes, salt, and black pepper for the cozy garlic butter pasta recipe foundation.
Add drained pasta directly to the butter mixture, tossing gently to coat every strand. Pour reserved pasta water slowly while tossing, allowing the starchy liquid to emulsify and create a silky, cohesive sauce.
Remove from heat and add lemon juice, fresh parsley, and fresh basil, tossing once more to combine. Divide among bowls and top with grated Parmesan cheese and panko breadcrumbs for added texture and elegance.
