Ingredients
Method
Cook the pasta
- Bring a large pot of water to a rolling boil. Add 1 tablespoon kosher salt.
- Add 12 ounces bowtie pasta and cook according to package directions until al dente, usually 9 to 11 minutes.
- Reserve 1 cup pasta cooking water, then drain the pasta and set aside. Toss with 2 tablespoons olive oil if you will hold it for a few minutes.
Brown the beef
- While pasta cooks, heat a large skillet over medium-high heat.
- Add 1 pound ground beef and season with 1 teaspoon salt, 1/2 teaspoon pepper, and 1/2 teaspoon Italian seasoning.
- Cook, breaking up with a spoon, until browned and no pink remains, about 4 to 6 minutes. Drain excess fat if needed and transfer beef to a plate.
Build the sauce
- Reduce heat to medium and add 2 tablespoons butter to the same skillet.
- Add 1 small chopped onion and sauté until translucent, about 3 to 4 minutes.
- Add 4 cloves minced garlic and cook until fragrant, about 30 to 45 seconds; avoid browning the garlic so it does not get bitter.
- Pour in 1 cup beef broth and scrape up browned bits from the pan. Let simmer 2 minutes to reduce slightly.
Finish the creamy sauce
- Stir in 1 1/2 cups heavy cream and bring just to a gentle simmer, about 2 to 3 minutes. Do not boil hard.
- Whisk in 1 1/2 cups freshly grated Parmesan cheese until melted and smooth. If sauce seems too thick, thin with up to 1/2 cup reserved pasta water, 2 tablespoons at a time, until you reach desired consistency.
- Return browned beef to the skillet and add 1/2 cup thawed peas and 1/4 teaspoon crushed red pepper flakes if using. Heat through 1 to 2 minutes.
Combine and serve
- Add cooked bowtie pasta to the sauce and toss to coat evenly. If the sauce needs loosening, stir in a splash of reserved pasta water.
- Taste and adjust seasoning with salt and pepper. Garnish with chopped fresh parsley and extra Parmesan.
- Serve immediately while hot, with extra cracked black pepper on top.
Notes
Use freshly grated Parmesan for the creamiest texture and best flavor. To prevent a grainy sauce, avoid boiling heavy cream. If sauce separates, whisk in 1 to 2 teaspoons cornstarch dissolved in cold water over low heat to bring it back together.
