How to Make and Thicken Spaghetti Sauce

Step 1

Add oil to a deep skillet over medium-high heat. Add ground beef and cook for a few minutes until fully cooked. Break down the ground beef using a wooden spoon.

Step 2

Transfer the cooked ground beef to a plate lined with paper towels.

Step 3

Reduce the heat to medium, and add chopped onions.

Step 4

Sauté for a few minutes and add garlic. Cook for 1 more minute.

Step 5

Add crushed tomatoes, chicken broth, tomato paste, basil, oregano, and cooked beef.

Step 6

Stir everything together and season with salt and pepper.

Step 7

Bring to a boil and then reduce heat to low. Cover with a lid and simmer until onions are tender for about 15-20 minutes.

Step 8

Remove the lid. If the sauce is too thin, simmer longer or until it reaches the preferred consistency. (If you’d like to thicken the sauce faster, you can add one of the following to your sauce: tomato paste/sauce, roux, cornstarch slurry, egg yolks, or mash potatoes.)

Step 9

Stir in parmesan. Serve warm with cooked spaghetti.
