Ingredients You’ll Need
This recipe uses five main ingredients to create a comforting pasta dinner without requiring a complicated homemade sauce.
1. Lean Ground Beef
You’ll need 1 pound of lean ground beef.
Ground beef provides a hearty, savory foundation for the tomato sauce. Lean beef is a convenient choice because it produces less excess grease, helping keep the finished sauce rich without becoming oily.
Brown the beef in a skillet before adding it to the slow cooker. Break it into small crumbles as it cooks, then drain away any excess fat.
2. Spaghetti Sauce
Use one 24-ounce jar of spaghetti sauce or marinara sauce.
A good-quality jarred sauce makes this recipe especially convenient. Choose a smooth or chunky variety depending on your preference.
Since the ingredient list is short, use a sauce you already enjoy. A flavorful marinara provides much of the seasoning and tomato flavor for the finished dish.
3. Canned Diced Tomatoes
Add one 14.5-ounce can of diced tomatoes, including the juices.
The tomatoes provide extra texture, moisture, and fresh tomato flavor. They also help create a generous sauce that coats the tagliatelle beautifully.
4. Tagliatelle Pasta
You’ll need 1 pound of tagliatelle pasta.
Tagliatelle is a long, flat ribbon pasta that works wonderfully with rich meat sauces. Its broad surface helps the beef and tomato mixture cling to each strand.
Cook the pasta separately according to the package directions and combine it with the sauce shortly before serving.
5. Shredded Mozzarella Cheese
Use 1 cup of shredded mozzarella cheese.
Mozzarella melts into a soft, creamy topping that complements the savory beef and tomato sauce.
For the best melting texture, shred the cheese yourself if possible. Add it at the end of cooking so it melts gently without becoming overcooked.
How to Make 5-Ingredient Slow Cooker Tagliatelle Supper
Step 1: Brown the Ground Beef
Heat a large skillet over medium heat. Add the ground beef and break it into small crumbles with a wooden spoon.
Cook until the beef is browned and no longer pink, then drain off excess grease.
Browning the beef before slow cooking helps develop a deeper, savory flavor and prevents unnecessary grease from collecting in the sauce.
Pro tip: Drain the beef well before transferring it to the slow cooker for a richer, less oily tomato sauce.
Step 2: Prepare the Beef and Tomato Sauce
Transfer the cooked ground beef to your slow cooker.
Add the jar of spaghetti sauce and the can of diced tomatoes, including their juices. Stir everything together until the beef is evenly distributed throughout the tomato mixture.
Cover with the lid and cook:
- LOW: 4–6 hours.
- HIGH: 2–3 hours.
The sauce will gradually develop a deeper flavor as the beef cooks in the tomatoes and marinara.
Pro tip: Keep the lid closed as much as possible to maintain a consistent cooking temperature.
Step 3: Cook the Tagliatelle Separately
When the sauce is nearly ready, bring a large pot of salted water to a boil.
Add the tagliatelle and cook according to the package directions until tender. If you prefer a slightly firmer texture, cook it just until al dente.
Drain the pasta, reserving a small amount of pasta water if desired.
Cooking the tagliatelle separately is the best way to control its texture. Adding dry pasta to the slow cooker can make it difficult to predict the cooking time and may leave you with noodles that are too soft or unevenly cooked.
Pro tip: Have the pasta ready shortly before serving so it stays tender and doesn’t sit in the sauce for too long.
Step 4: Combine the Pasta and Beef Sauce
Add the drained tagliatelle to the slow cooker with the finished beef and tomato sauce.
Gently toss everything together until the pasta is evenly coated.
If the sauce seems too thick, add a small splash of reserved pasta water and stir until it reaches your preferred consistency.
Pro tip: Add the pasta gradually if your slow cooker is small, making sure there is enough room to toss everything without breaking the ribbons.
Step 5: Add the Mozzarella Cheese
Sprinkle the shredded mozzarella over the pasta.
Cover the slow cooker for approximately 5–10 minutes, or until the cheese melts.
Once the mozzarella is soft and gooey, gently toss the pasta again if desired, or leave the cheese on top for a delicious, cheesy finish.
Avoid cooking the pasta for an extended period after adding it. The goal is simply to warm it through and melt the cheese.
Step 6: Serve Warm
Divide the tagliatelle and beef sauce among serving bowls.
Serve immediately while the pasta is tender, the tomato sauce is warm, and the mozzarella is melted.
Pair it with garlic bread, a fresh green salad, or steamed vegetables for an easy and satisfying family dinner.
What to Serve with Tagliatelle Supper
This hearty beef and tomato pasta pairs beautifully with simple sides that complement its rich sauce without overpowering the meal.
- Garlic bread: Perfect for soaking up the extra tomato sauce.
- Fresh green salad: Crisp lettuce, cucumber, and a light vinaigrette add freshness.
- Steamed green beans: A simple vegetable side that balances the richness of the pasta.
- Roasted broccoli: Slightly crisp edges and tender centers provide a pleasant contrast to the soft noodles.
- Warm dinner rolls: An easy addition to a comforting family-style supper.
- Roasted zucchini: A mild, savory vegetable that works well with tomato-based dishes.
- Parmesan cheese: Offer freshly grated Parmesan at the table for extra flavor.
For a classic family dinner, serve the tagliatelle with garlic bread and a crisp green salad.
Helpful Tips for the Best Results
- Cook the pasta just before serving: Tagliatelle can become mushy if left in the slow cooker for hours.
- Drain the ground beef thoroughly: Excess grease can make the tomato sauce oily.
- Choose a marinara sauce you love: The sauce is one of the main sources of flavor in this five-ingredient recipe.
- Use the correct cooking time: Slow cookers vary, so check that the sauce is hot and the beef is fully cooked.
- Add the mozzarella at the end: This helps it melt smoothly without becoming overcooked.
- Save a little pasta water: The starchy water can help loosen the sauce and help it cling to the noodles.
- Avoid overmixing: Toss the tagliatelle gently to keep the long ribbons from breaking.
- Serve promptly: The pasta has its best texture when freshly combined with the sauce.
- Adjust the seasoning if needed: Taste the sauce before serving and add salt or black pepper if desired. These are optional additions, not part of the original five ingredients.
Easy Variations
One of the best things about this recipe is how flexible it can be. Keep the original five ingredients for simplicity or try one of these variations to create a slightly different dinner.
Italian Sausage Tagliatelle
Replace the ground beef with Italian sausage for a richer, more seasoned sauce. Remove the sausage from its casings if necessary, brown it thoroughly, and drain excess grease before adding it to the slow cooker.
Cheesy Beef Tagliatelle
For an extra-cheesy finish, add a little more mozzarella or sprinkle Parmesan cheese over each serving.
Additional cheese changes the original five-ingredient count but creates an even richer pasta dinner.
Spicy Tomato Beef Pasta
Choose a spicy marinara sauce or add a pinch of red pepper flakes for gentle heat.
Vegetable-Loaded Tagliatelle
Add chopped bell peppers, sautéed mushrooms, or finely diced onions to the beef sauce. Cook vegetables that release significant moisture before adding them if you want to keep the sauce thick.
Different Pasta Shapes
Don’t have tagliatelle? No problem. Try one of these alternatives:
- Fettuccine: Similar flat ribbons that pair well with meat sauce.
- Linguine: Long pasta with a slightly narrower shape.
- Penne: Tubes that hold sauce inside and out.
- Rigatoni: Large ridged tubes that work especially well with chunky meat sauce.
Cook whichever pasta you choose separately according to its package directions, then combine it with the finished sauce.
Skip the Mozzarella
If you prefer a traditional beef and tomato sauce without cheese, simply leave out the mozzarella. The pasta will still be hearty, flavorful, and satisfying.
Storage Instructions
Allow leftover pasta to cool slightly, then transfer it to airtight containers and refrigerate within 2 hours of cooking.
- Refrigerator: Store for 3–4 days.
- Freezer: Freeze for up to 3 months for best quality.
For the best texture, store the beef and tomato sauce separately from the cooked tagliatelle whenever possible. This helps prevent the pasta from absorbing too much sauce and becoming overly soft.
If the pasta and sauce are already combined, you can still refrigerate or freeze them together. The texture may be softer after reheating.
How to Reheat Leftover Tagliatelle
Reheating in the Microwave
Place a serving in a microwave-safe dish and add a small splash of water or tomato sauce.
Cover loosely and heat in short intervals, stirring halfway through, until the food is steaming hot throughout.
Reheating on the Stovetop
Transfer the pasta to a skillet or saucepan over medium-low heat.
Add a little water or extra marinara sauce to loosen the mixture. Stir gently and heat until warmed through.
If you’re reheating the beef sauce separately, you can prepare fresh tagliatelle and combine it with the warm sauce for a better pasta texture.
Can You Freeze This Pasta Dinner?
Yes. The beef and tomato sauce freezes well, making it a convenient option for future meals.
Allow the sauce to cool, then transfer it to a freezer-safe container and freeze for up to 3 months for best quality.
Thaw overnight in the refrigerator and reheat thoroughly. For the best results, cook fresh tagliatelle when you’re ready to serve.
Frequently Asked Questions
Can you put uncooked pasta in the slow cooker?
Some slow cooker recipes cook pasta directly in the sauce, but the timing and liquid requirements can be tricky. For this recipe, cooking the tagliatelle separately produces more consistent results and helps prevent the noodles from becoming mushy.
Can I substitute Italian sausage for ground beef?
Yes. Italian sausage works well and adds extra seasoning and a richer flavor. Brown it thoroughly in a skillet and drain excess grease before adding it to the sauce.
Can I use a different type of pasta?
Absolutely. Fettuccine, linguine, penne, and rigatoni are all suitable alternatives. Cook the pasta according to the package instructions before mixing it with the finished beef sauce.
Can I make the sauce ahead of time?
Yes. Prepare the beef and tomato sauce in the slow cooker, cool it promptly, and refrigerate it in an airtight container. Reheat the sauce when you’re ready to eat, then toss it with freshly cooked tagliatelle and add the mozzarella.
Can I leave out the mozzarella?
Yes. The beef and tomato sauce is delicious on its own. Simply omit the cheese if you prefer a more traditional tomato-based meat sauce.
Why should I cook the pasta separately?
Tagliatelle can absorb liquid and soften significantly during prolonged cooking. Preparing it separately allows you to control the texture and combine it with the sauce just before serving.
Can I add extra vegetables?
Yes. Bell peppers, mushrooms, and onions are good options. Sauté vegetables that release a lot of moisture before adding them to help maintain the sauce’s consistency.
Is this recipe good for meal prep?
Yes. The beef and tomato sauce can be prepared in advance and portioned for later meals. For the best results, store the sauce and pasta separately and cook fresh tagliatelle when possible.
