First Step: Cook the Bowtie PastaBring a large pot of salted water to a boil. Add 12 ounces of bowtie pasta and cook according to package directions until al dente, typically about 8–10 minutes. Reserve 1 cup of the pasta water before draining, then set the pasta aside. This reserved water will be useful later to adjust sauce consistency for the perfect creamy texture.

Second Step: Brown the Ground BeefIn a large skillet over medium heat, add 2.25 pounds of ground beef. Break the meat into small pieces and cook until no longer pink and fully browned, about 6–8 minutes. For richer flavor, use high-quality beef. Drain excess fat to avoid a greasy casserole. Optionally, add 1 chopped medium onion and 2 minced garlic cloves to the skillet and sauté with the beef until softened, approximately 3–4 minutes, enhancing taste layers.

Third Step: Create the Creamy Cheese SauceReduce heat to medium. Stir in 16 ounces of cubed processed cheese and 8 ounces of softened cream cheese to the browned beef mixture. Add 1 can (10.5 ounces) of cream of chicken soup and 1 can (10 ounces) of diced tomatoes with chilies, undrained. Season with salt, pepper, and Italian herbs to taste. Cook while stirring continuously until the cheeses melt completely and the sauce becomes smooth and creamy. If the sauce appears too thick, gradually incorporate reserved pasta water until desired creaminess is achieved.

Fourth Step: Add Optional Vegetables (If Using)If you prefer vegetables, sauté chopped bell peppers or mushrooms separately until tender, about 5 minutes, and stir them into the sauce mixture. This step adds extra nutrition and flavor complexity to your velveeta beef bowtie pasta casserole.

Fifth Step: Combine Pasta and SauceAdd the cooked bowtie pasta to the skillet with the creamy beef cheese sauce. Toss gently to coat every piece of pasta evenly with the luscious sauce. Adjust sauce thickness one last time with reserved pasta water if necessary to ensure the perfect balance that clings well but isn’t overly heavy.

Sixth Step: Optional Baking for a Casserole FinishFor a delightful baked velveeta beef bowtie pasta casserole variation, preheat your oven to 350°F (175°C). Transfer the skillet mixture into a greased casserole dish. You may add additional shredded cheese on top for a golden crust. Bake uncovered for 15 minutes or until bubbly and cheese is melted. Allow to rest briefly before serving.

Final Step: Serve and GarnishServe the creamy, cheesy beef and bowtie pasta warm. Top with shredded Parmesan cheese and red pepper flakes if desired for extra flavor and presentation. This hearty dish pairs well with a crisp green salad or steamed vegetables for a complete meal.
