Ina’s shrimp scampi is one of the simplest recipes I tested and comes together in under 20 minutes. You’ll start by cooking some linguine in salted, boiling water with a drizzle of oil in it. While the pasta is cooking, heat butter and olive oil in a heavy-bottomed pan. Add garlic and sauté for just a minute, then add your shrimp, salt, and pepper. Cook until the shrimp turn pink, then remove the pan from the heat. Add lemon juice and zest, red pepper flakes, chopped fresh parsley, and slices of lemon. To finish it, toss everything together then add your cooked pasta.
