One-Pan Ground Beef Pasta for Busy Nights

The short answer

For one-pan ground beef pasta, brown 1 pound of ground beef to 160°F (71°C), spoon off pooled fat, and soften onion and carrot in the same pot. Add one undrained 14.5-ounce can of diced tomatoes plus exactly 2 cups broth, then stir in 8 ounces Ronzoni rigatoni. Simmer uncovered and begin checking at the package's 13-minute al dente mark. Add hot water in measured 1/4-cup portions only if the pasta is firm and the sauce is dry.

The sauce has two liquid inputs

The pasta cooks in the sauce, so this recipe does not hide a freehand pour. Its starting liquid is the complete contents of one 14.5-ounce can of diced tomatoes plus 2 cups unsalted or no-salt-added beef broth. The tomato juice contributes to the cook; do not drain the can.

Keep 1 cup hot water beside the stove for measured corrections, but do not add it automatically. Different burners, pot widths, and pasta batches lose water at different rates. A dry pan with firm rigatoni gets 1/4 cup at a time. A wet pan gets more simmering, not more liquid.

Ronzoni's current conventional directions list 13 minutes for al dente rigatoni, 14 for firm, and 15 for tender when boiled in abundant water and drained. A meat-and-tomato sauce is different, so 13 minutes is the first bite test rather than a guaranteed finish.

Ingredients for four portions

• 1 pound (454 g) 90% lean ground beef
• 8 ounces (227 g) Ronzoni rigatoni, weighed dry
• 1 can diced tomatoes, 14.5 ounces (411 g), undrained
• 2 cups unsalted or no-salt-added beef broth
• 1 cup hot water held in reserve; use only as directed
• 1 medium yellow onion, about 6 ounces (170 g), cut into 1/4-inch dice
• 1 medium carrot, about 4 ounces (113 g), cut into 1/4-inch dice
• 3 garlic cloves, finely chopped
• 2 tablespoons tomato paste
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• 1/2 teaspoon fine salt, divided, plus more only after tasting
• 1/4 teaspoon black pepper
• 2 ounces (57 g) Parmesan, finely grated by weight
• 1 tablespoon lemon juice or red wine vinegar
• 2 tablespoons chopped parsley, optional

Use a wide 5- to 6-quart pot or a deep 12-inch skillet. Rigatoni needs room to settle into the sauce and be stirred without throwing hot liquid over the rim. Keep a heatproof bowl ready for rendered fat and a food thermometer ready for the beef.

Salt differs among tomatoes, broth, and Parmesan. Check all three labels and begin with the measured 1/2 teaspoon. Taste only after the cheese has melted.

Step 1: prepare before touching raw meat

Cut the onion and carrot, grate the Parmesan, and measure the pasta, liquids, tomato paste, and seasonings before opening the beef. Put the dry seasonings into one small bowl so hands that have touched raw meat do not return to the jars.

Keep raw beef and its plate away from Parmesan, lemon, and parsley that will not receive a full cook. Wash hands, the raw-meat plate, utensils, and contacted surfaces with hot, soapy water before handling cooked food.

Step 2: brown the beef and check 160°F

Heat the empty pot over medium-high heat. Add the beef and break it into pieces no larger than 1/2 inch. Press it into one layer and leave it undisturbed for 2 minutes, then stir and continue cooking for about 5 to 7 minutes.

Time and brown colour do not establish safety. Check several thick clusters with a food thermometer and continue cooking until each reaches at least 160°F (71°C), the current CDC and FoodSafety.gov endpoint for ground beef. Wash the thermometer probe after it touches beef that has not yet reached that temperature.

If fat forms a visible pool, turn off the heat, tilt the pot carefully, and spoon the excess into the heatproof bowl. Leave a thin coating in the pot for the vegetables. Let removed fat cool before discarding it; do not pour hot fat down the sink.

Step 3: build the aromatic base

Return the pot to medium heat. Add the onion, carrot, and 1/4 teaspoon salt to the cooked beef. Cook for 7 to 9 minutes, stirring every minute or two, until the onion is translucent and a carrot piece is tender at the centre.

Add the garlic, tomato paste, oregano, basil, and black pepper. Stir for 1 minute, spreading the paste through the beef and vegetables. If a dry spot begins to darken, add 1 tablespoon from the measured broth and scrape immediately; it still belongs to the fixed 2 cups.

Step 4: dilute the sauce before adding pasta

Pour in the undrained tomatoes and all remaining measured broth. Scrape the pot base so no browned residue is trapped beneath the rigatoni. Bring the sauce to a full boil over medium-high heat.

Add the 8 ounces rigatoni and stir until the tubes separate. Reduce the heat to maintain a steady uncovered simmer. Stir every 1 to 2 minutes, moving around the edge and across the base. Keep the pasta mostly below the sauce between stirs.

Begin checking at 13 minutes. Bite one tube from the centre and one from the edge. Continue toward 14 or 15 minutes if the pasta is firmer than you want, but check the sauce level at the same time. Use the matching measured correction rather than adding all the reserved water.

Step 5: finish after the pasta is tender

When the rigatoni is tender and a shallow layer of sauce still moves around it, turn off the heat. Add the Parmesan in three portions, folding until each portion melts before adding the next.

Fold in the lemon juice or vinegar and the remaining 1/4 teaspoon salt. Rest the pot uncovered for 5 minutes so the sauce settles around the tubes, then taste before adding more salt. Add parsley after the rest.

The recipe makes four portions. Before cooking, each represents 4 ounces (113 g) ground beef, 2 ounces (57 g) dry rigatoni, one quarter of the tomatoes and vegetables, 1/2 cup broth, and 1/2 ounce (14 g) Parmesan. The reserved water is not divided because it is used only if the pan needs it.

What if the rigatoni is firm and the sauce is dry?

If a centre and edge piece are still firm and the sauce no longer moves when stirred, add exactly 1/4 cup hot water. Stir, return to a steady simmer, and cook for 2 minutes before checking again.

Repeat with another 1/4 cup only if the rigatoni remains firm and the sauce is dry again. Keep a note of the total if you repeat the dish with the same pasta, pot, and burner. Do not add Parmesan until the pasta texture is right.

If firm pasta sits in visible liquid, do not add water. Continue simmering uncovered for 2 minutes, stirring once, then check again. The sauce already in the pot needs time to enter the rigatoni.

What if the pasta is tender but the sauce is thin?

Turn off the heat, add the Parmesan, and give the pot its full 5-minute rest before making another change. The cheese and rest can tighten a sauce that looks loose over active heat.

If liquid still pools after the rest, return the pot to low heat for 1 minute while folding gently. Avoid a hard boil because the rigatoni is already tender. Do not add raw flour directly; it can clump and this short finishing stage does not provide a reliable cooking period.

If the sauce is too thick after resting, fold in 2 tablespoons hot water. Add a second tablespoon only if the first is fully mixed and the sauce still does not move around the pasta.

Fat management without drying out the sauce

Ground beef can release very different amounts of fat. Remove only a visible pool after the beef reaches 160°F; a thin film on the pot is useful for softening the vegetables. Draining the beef completely can leave the onion and carrot sticking before the tomato arrives.

If you use beef leaner than 90%, watch the pan during the vegetable stage. Add 1 teaspoon olive oil only if the surface is dry and the vegetables are catching. If you use a fattier blend, expect to spoon off more. Do not compensate for excess fat by adding extra tomato or broth; remove the fat so the sauce arithmetic stays intact.

Substitutions with stated limits

• Small rigatoni or penne can replace standard rigatoni by weight. Use its own package time as the first check and expect liquid needs to differ.
• Ground turkey can replace beef by weight, but it must reach 165°F (74°C), not the beef endpoint of 160°F.
• Unsalted vegetable broth can replace beef broth without changing the 2-cup starting amount.
• Pecorino Romano can replace Parmesan by weight. Check the label and taste before adding final salt.
• Add 3 ounces baby spinach only after the pasta is tender. Fold it in before the cheese, cover off heat for 2 minutes, and check that all leaves have wilted.
• Serve ricotta, chilli flakes, or extra herbs at the table rather than adding an unmeasured wet ingredient during pasta cooking.

Do not substitute fresh, gluten-free, whole-grain, or filled pasta and assume the same liquid or 13-minute checkpoint. Their formulations and cooking methods differ. For a tomato-based pasta method built for a smaller shape and batch, see the published tomato orzo for two.

Ronzoni lists wheat in its rigatoni and says it may contain eggs; Parmesan is a dairy ingredient. Select labelled alternatives appropriate to the people eating and follow their directions rather than assuming identical behaviour.

Can you halve or double the recipe?

For two portions, use 8 ounces beef, 4 ounces rigatoni, 7.25 ounces undrained diced tomatoes, 1 cup broth, 1 ounce Parmesan, and half every vegetable and seasoning. Hold 1/2 cup hot water in reserve and add it only in measured 1/4-cup portions if needed. Use a deep 10-inch skillet.

For eight portions, use 2 pounds beef, 16 ounces rigatoni, two 14.5-ounce cans tomatoes, 4 cups broth, 4 ounces Parmesan, and twice every other ingredient. Hold 2 cups hot water in reserve, not in the starting sauce. Use a wide pot larger than 7 quarts or make two standard batches; a deeper pot will brown and reduce differently.

Store and reheat ground beef pasta safely

Divide leftovers among shallow containers and refrigerate within 2 hours at 40°F (4°C) or below. Discard food left at room temperature for more than 2 hours, or more than 1 hour when the outside temperature is above 90°F (32°C).

Reheat leftovers to 165°F (74°C), checking the centre with a food thermometer. Add 1 tablespoon water per portion, cover, and stir halfway through heating. Add more water only after the centre reaches temperature and only if the sauce needs loosening.
