Creamy Cheddar Beef Spaghetti Skillet (One-Pan Comfort) Step-by-step instructions

Before you start

Before starting, gather all the necessary ingredients and equipment to ensure a smooth cooking process. Grate the cheddar cheese from a fresh block and cut the cream cheese into small cubes so it melts quickly and evenly.

Measure out the heavy cream and butter, and mince the fresh parsley. Bring a large pot of salted water to a boil for the spaghetti. Having everything prepped and ready to go prevents the cheese sauce from overcooking or scorching while you search for ingredients.

Instructions

Boiling the Pasta to Al Dente

1. 1Boil the Spaghetti
   Boil the spaghetti in a large pot of salted water according to the package directions until al dente. Drain the pasta thoroughly, reserving a splash of pasta water, and set it aside. Do not rinse the pasta, as the starch helps the sauce stick.
   Look for The pasta is tender but still has a slight bite.
   Tip Save half a cup of pasta water before draining to adjust the sauce thickness later.

The spaghetti should be cooked until it is just al dente, meaning it still has a slight bite in the center. It will continue to cook slightly when tossed in the hot cheese sauce later. Drain the pasta thoroughly but do not rinse it, as the natural starches remaining on the surface of the noodles are essential for helping the rich cheddar sauce cling to the spaghetti.

Browning the Ground Beef

2. 2Brown the Ground Beef
   Melt the butter in a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a wooden spoon, until it is fully browned and cooked through, reaching a safe internal temperature of 160°F (71°C). Drain any excess grease if desired.
   Look for The beef is fully browned with no pink remaining.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Let the beef sear for a minute before stirring to build a deeper flavor.

The ground beef should be completely browned with no pink remaining, releasing a rich, savory aroma throughout the kitchen. Look for a deep golden-brown crust on the crumbled pieces of meat, which indicates maximum flavor development. The butter should be fully integrated, leaving a glistening, flavorful base at the bottom of the skillet ready for the sauce.

Melting the Cheese and Combining

3. 3Melt the Cream Cheese
   Reduce the heat to medium-low. Stir the heavy cream and cream cheese into the skillet with the beef, stirring constantly until the cream cheese is fully melted and incorporated into a smooth liquid.
   Look for The sauce is smooth and the cream cheese is fully dissolved.
   Tip Using room temperature cream cheese helps it melt much faster.
4. 4Add Cheddar and Toss
   Gradually fold in the shredded cheddar cheese, stirring continuously until melted and smooth. Add the cooked spaghetti to the skillet and toss until the pasta is completely coated in the velvety cheese sauce. Garnish with minced fresh parsley and serve immediately.
   Look for The cheese is fully melted and the pasta is thoroughly coated.
   Tip If the sauce is too thick, stir in a tablespoon of the reserved pasta water.

The finished skillet should showcase a thick, glossy, golden cheese sauce that completely coats the spaghetti and ground beef. The sauce should be smooth and bubbling gently, with no separation or graininess.

When you lift a forkful of pasta, the cheese should stretch slightly and cling beautifully to the noodles without dripping excessively, topped with a vibrant green sprinkle of fresh parsley.

Common mistakes

One common mistake is using pre-shredded cheddar cheese, which contains starches that prevent smooth melting and lead to a gritty, separated sauce. Another error is letting the heavy cream boil too rapidly after adding the cheeses; high heat can cause the dairy proteins to clump and break, ruining the silky texture.

Always melt the cheese over medium-low heat, stirring constantly. Finally, do not overcook the spaghetti during the initial boil, as mushy pasta will break apart when tossed with the heavy beef and cheese mixture.

How to tell it’s done

The dish is fully cooked and ready to serve when the ground beef has reached a safe internal temperature of 160°F (71°C) and the cheese sauce is completely melted, smooth, and bubbling gently around the edges of the skillet.

The pasta should be thoroughly coated and heated through. You can verify the beef's doneness using an instant-read digital food thermometer inserted into the center of the beef crumbles before mixing them into the final cheese sauce.
