• 1 lb (450 g) ground beef (or beef/pork mix)
• 1 can (14 oz / 400 g) crushed tomatoes
• 2 tbsp tomato paste
• 1/2 cup (120 ml) beef broth or red wine
• 1 tsp dried oregano
• 1/2 tsp dried thyme

How to Make (Step-by-Step)

1. Heat olive oil in a skillet over medium heat.
2. Add onion and garlic, sauté until fragrant.
3. Stir in ground beef, breaking it apart with a spoon, and cook until browned.
4. Add tomato paste, crushed tomatoes, and broth (or wine).
5. Season with oregano, thyme, salt, and pepper.
6. Simmer uncovered for 20–25 minutes until thickened. Set aside to cool slightly.
7. Bring a large pot of salted water to a boil.
8. Cook rigatoni until just al dente (slightly undercooked, as it will bake further).
9. Drain and cool slightly so it’s easier to handle.
10. Transfer the cooled beef ragu into a piping bag (or use a spoon).
11. Carefully stuff each rigatoni with the meat filling.
12. Arrange stuffed rigatoni side by side in a lightly greased baking dish.
13. Sprinkle generously with mozzarella and Parmesan cheese.
14. Bake at 375°F (190°C) for 20–25 minutes, until cheese is golden and bubbly.
15. Sprinkle with fresh parsley before serving.
16. Serve hot with garlic bread or a fresh green salad.

Heat the oil & sweat the aromatics

Start by warming the olive oil. I always toss the onion in first and let it get soft and sweet. Garlic goes in once the onion looks translucent. Your kitchen will smell like you’ve got your life together — FYI, that illusion matters.

Brown the meat properly

Push the meat around and break it up as it cooks. Browning adds a nutty depth. Add tomato paste next and let it toast for a minute before you deglaze with broth or wine. Trust me, the extra two minutes matter.

Simmer until thick

Let the sauce bubble uncovered until it thickens. You want a ragu that clings to the pasta, not a soup. If it seems too thin, simmer five more minutes. If it thickens too much, splash in a little broth.

Cook pasta al dente

Under-cook the rigatoni slightly. It will finish in the oven and soak up lovely sauce. Overcooked tubes turn mushy. Nobody wants soggy heroics.

Pro Tips for the Best Results

• Fill while warm: The ragu flows easier when slightly warm, so stuffing becomes fast.
• Use a piping bag: I use a piping bag with a wide tip; it turns stuffing into a one-handed, efficient joy.
• Grease the pan well: Brush or spray the dish so tubes don’t stick.
• Don’t skimp on cheese: Mozzarella gives stretch; Parmesan gives punch. I always add both.
• Make it ahead: Assemble the night before, cover tightly, and bake straight from the fridge (add 5–10 minutes).
• Add texture: Toast breadcrumbs with butter and sprinkle for a crunchy top.

Fun Variations & Topping Ideas

Variations

• Add sweet corn for a crunchy-sweet contrast.
• Crumble cooked Italian sausage into the ragu for a spicier kick.
• Use leftover shredded roast beef if you want to speed things up.
• Swap rigatoni for cannelloni shells if you want a different look.
• Use this as the base for a loaded potato soup — take the ragu, toss it into a pot of potatoes, cream, and shredded cheese for a hearty twist.

Toppings

• Bacon bits for salty crunch
• Extra shredded cheddar for a sharper finish
• Chopped green onions for fresh bite
• Dollops of sour cream if you want creamy tang
• Fresh basil leaves for summer brightness

Storing and Reheating

• Refrigerate leftovers in an airtight container for up to 3 days.
• Freeze portions in freezer-safe containers for up to 3 months.
• To reheat from fridge: bake at 350°F (175°C) for 12–15 minutes covered with foil, then uncover for 5 minutes to crisp.
• To reheat from frozen: thaw overnight in the fridge, then follow the above reheating method.
• Microwave works in a pinch, but the oven brings back the best texture.

Frequently Asked Questions (FAQ)

How do I prevent soggy rigatoni?

Cook the pasta slightly under al dente and drain well. Let the ragu reduce until it thickens; a watery sauce causes sogginess.

Can I use ground turkey instead of beef?

Yes, but turkey delivers a milder flavor. Add a splash of Worcestershire or a pinch of smoked paprika to boost savoriness.

Do I need to stuff every tube?

Stuffing every tube creates uniform flavor in every bite, but you can mix stuffed and unstuffed rigatoni if you’re short on time.

How do I make this vegetarian?

Swap the beef for sautéed mushrooms, lentils, or a plant-based ground mix. Add umami boosters like soy sauce or miso to keep depth.

Can I assemble ahead of time?

Absolutely. Assemble and refrigerate. Bake when guests arrive. You’ll look effortlessly on top of things. IMO, this trick saves lives.
