Slow Cooker Cheesy Taco Bowtie Pasta That Doesn't Turn to Mush

Jump to Recipe ↓

The first time I made Slow Cooker Cheesy Taco Bowtie Pasta, the bowties failed in two directions at once. The wings went soft and floppy. The little pinched knot in the middle stayed chalky. Same noodle, both problems.

I had dumped a box of dry farfalle straight into the crock, the way a lot of recipes tell you to. My family ate it anyway, because cheese forgives a lot. But I knew the fix wasn’t in the sauce. It was in the shape of the pasta.

Here’s the thing about bowties. The center is folded over on itself, so it’s roughly twice as thick as the edges. Cook it until the knot is tender and the wings have already given up. So this version gives the pasta a short head start on the stove, four minutes shy of the box time, and then lets it finish in the taco sauce for fifteen minutes. The knot catches up. The wings keep their shape.

Everything else is taco night in one pot. Browned beef with toasted spices, Rotel, a glossy sauce built on Velveeta and cream cheese, and then sharp cheddar and Monterey Jack folded in at the very end, off the heat. It feeds eight, and it reheats better than you’d expect.

Why This Slow Cooker Cheesy Taco Bowtie Pasta Works

The pasta gets a head start, not a full boil. Dry pasta drinks a lot of liquid, and every slow cooker runs at its own temperature. One crock gives you taco soup. Another gives you a gluey brick. When the bowties are already mostly cooked, the only variable left is fifteen minutes on HIGH, and that’s easy to control.

The spices hit hot fat before they hit the crock. A taco packet stirred into a cold slow cooker tastes flat by the end, especially under two kinds of cheese. Dairy mutes chili. So after draining the beef, I leave about a tablespoon of fat in the pan and stir the seasoning, cumin, and chili powder through it for one minute. That minute is the difference between “taco-ish” and actual taco flavor.

The beef gets drained hard. Whatever fat stays in the pan ends up as an orange slick floating on the cheese sauce. Velveeta can hold a little fat in suspension. Not two pounds’ worth.

The cheeses go in a specific order. Velveeta has emulsifying salts in it, which is why it melts so smooth. Melted first with the cream cheese, it becomes the glue that holds the real cheese together. Shredded cheddar, on the other hand, tightens up and squeezes out its fat if it meets a bubbling sauce. That’s where grainy taco pasta comes from. So the cheddar and Jack go in last, with the cooker switched to WARM.

The base doesn’t cook all day. The beef is already cooked when it goes in. The crock only needs to soften the onion and pull the flavors together, which takes about four hours on LOW. Push it past six and the onion collapses to nothing while the tomato around the edge of the crock darkens and turns bitter.

Salt waits until the end. Taco seasoning, Rotel, salsa, and Velveeta all bring salt. Taste after the cheese is in, not before.

Ingredients

For the Taco Beef Base

2 pounds lean ground beef (90/10)
1 medium yellow onion, diced
3 garlic cloves, minced
1 packet (1 ounce) taco seasoning
1 teaspoon ground cumin
1 teaspoon chili powder
1 can (15 ounces) tomato sauce
1 can (10 ounces) Rotel diced tomatoes and green chiles, undrained
1 cup chunky salsa, medium
1 ½ cups low-sodium beef broth

For the Pasta and Cheese Sauce

1 box (16 ounces) bowtie pasta (farfalle)
8 ounces cream cheese, softened and cubed
8 ounces Velveeta, cut into ½-inch cubes
1 cup sharp cheddar, shredded from a block
1 cup Monterey Jack, shredded from a block
½ cup reserved pasta water, plus more as needed

For Serving

Sour cream
2 green onions, sliced
¼ cup chopped cilantro
1 cup crushed tortilla chips
1 lime, cut into wedges

Equipment: a 6-quart slow cooker at minimum (I use a 7-quart oval Crock-Pot), a large skillet, and a big pot for the pasta.

How to Make Slow Cooker Cheesy Taco Bowtie Pasta

Brown the beef and onion. Set a large skillet over medium-high heat. Add the ground beef and diced onion and cook for 8 to 10 minutes, breaking the meat into small crumbles as it browns. Keep the crumbles small. Big chunks slide off a bowtie instead of tucking into the folds.
Drain, then toast the spices. Tilt the skillet and spoon off the fat, leaving about 1 tablespoon behind. Add the garlic, taco seasoning, cumin, and chili powder. Stir for 1 minute, until the spices smell toasty and coat every bit of meat.
Load the slow cooker. Scrape the beef into the crock. Pour a splash of the broth into the hot skillet, scrape up the browned bits, and pour that in too. Add the tomato sauce, Rotel with its juice, salsa, and the rest of the broth. Stir well.
Slow cook the base. Cover and cook on LOW for 4 hours or HIGH for 2 hours. Leave the lid alone.
Par-boil the bowties. About 25 minutes before the base is done, bring a large pot of water to a boil. Salt it lightly, about 1 teaspoon, since the sauce already brings plenty. Cook the bowties for 4 minutes less than the package’s al dente time. For most 1-pound boxes, that’s 7 to 8 minutes. Bite the knot. It should be firm, with a small white dot in the center. Scoop out 1 cup of pasta water, then drain. Don’t rinse.
Melt the creamy cheeses. Switch the slow cooker to HIGH. Stir in the cream cheese and Velveeta until mostly melted, about 2 to 3 minutes. Cover for 5 minutes, then stir again until the sauce is smooth and orange all the way through.
Finish the pasta in the sauce. Fold in the bowties and ½ cup of the reserved pasta water. Cover and cook on HIGH for 15 minutes. Start checking at 12. You want the knot tender with just a little chew left.
Fold in the shredded cheese off the heat. Switch the cooker to WARM, or turn it off. Add the cheddar and Jack a handful at a time, folding gently until each handful melts. Taste now, and add salt only if it needs it. A squeeze of lime helps more than you’d think.
Rest and serve. Leave the lid off for 5 minutes so the sauce settles and thickens. If it gets too thick, loosen it with a splash of the remaining pasta water. Top with sour cream, green onions, cilantro, and crushed tortilla chips.

Tips for the Best Cheesy Taco Bowtie Pasta

Orange oil pooling on top? The beef wasn’t drained enough. For tonight, lay a paper towel flat on the surface for a second and lift it off. Next time, drain harder.

Shred your own cheese. Bagged shredded cheese is coated in starch so it won’t clump in the bag, and that same coating keeps it from melting clean. The one time I took the shortcut, the sauce had a fine, sandy texture by the second scoop. Block cheese, box grater, two minutes. Worth it.

Know your crock. Older slow cookers tend to run cooler than newer ones. If yours is new and runs hot, check the pasta at 10 minutes instead of 12.

Using a 4-quart slow cooker? Halve everything, including the pasta. The full batch fills a 6-quart to within about two inches of the rim, so a 4-quart won’t hold it.

Holding it for a potluck. It keeps on WARM for about an hour. Stir in 2 to 3 tablespoons of warm milk every 20 minutes, because the bowties keep soaking up sauce the whole time. After an hour, the texture starts to slide.

Heat level. With medium salsa and original Rotel, it lands mild to medium. For kids, use mild Rotel and mild salsa and put hot sauce on the table instead.

Variations

Half chorizo, half beef. My favorite swap. Replace 1 pound of the beef with Mexican pork chorizo, brown them together, drain well, and skip the chili powder. It tastes smokier and deeper, like it simmered all day on the stove.
Ground turkey. It works, but turkey is shy. Add an extra ½ teaspoon of cumin and ½ teaspoon of smoked paprika when you toast the spices, or it’ll taste like cheese and not much else.
Pepper Jack instead of Monterey Jack. Easy heat with no other changes.
Want beans? A drained and rinsed 15-ounce can of black or pinto beans goes in at step 3 with nothing else changed. I like this one better without. The beef and cheese stay front and center, and every forkful looks like taco pasta, not chili.
The cream-of-chicken-soup version. You’ll see it all over Facebook. I tried it once and wouldn’t do it again. The soup makes the whole pot taste like a church casserole wearing a taco costume, and it buries the chili flavor you worked to build.

Make-Ahead, Storing, Freezing, and Reheating

Make the base ahead. Cook the beef base through step 4, cool it, and refrigerate it for up to 2 days. When you’re ready, reheat it in the crock on HIGH for about 1 ½ hours, until it’s steaming, then pick up at step 5.

Freeze the base, not the finished pasta. The beef base freezes beautifully for up to 3 months. Thaw it overnight in the fridge. The finished pasta does not freeze well. The cheese sauce turns grainy once thawed, and the bowties swell and split. I’ve tried it twice, and I won’t freeze it a third time.

Don’t par-boil the pasta ahead of time. It sticks into a block in the fridge and goes soft in the sauce.

Fridge. Leftovers keep in an airtight container for 3 to 4 days. The sauce firms up a lot once cold. That’s normal.

Reheat in the microwave. Add 2 tablespoons of milk per 1 ½ cups of pasta, cover, and heat for 1 minute. Stir, then keep going in 30-second bursts until hot.

Reheat on the stove. Use a skillet over low heat with a splash of milk or broth. Stir often for 5 to 7 minutes. High heat will split the sauce, so keep it low.

Slow Cooker Cheesy Taco Bowtie Pasta FAQ

Can you put uncooked bowtie pasta in a slow cooker?

You can, but I wouldn’t. Dry bowties cook unevenly because the folded center is about twice as thick as the wings, so the edges turn soft before the knot is done. Every slow cooker heats differently, too, so the timing changes from one kitchen to the next. A short par-boil on the stove fixes both problems and only takes 8 minutes.

How long do bowties take to cook in a slow cooker?

About 15 minutes on HIGH once they’ve been par-boiled. Dry bowties need 25 to 35 minutes, and the results swing a lot depending on your crock.

Do I have to brown the ground beef first?

Yes. Raw ground beef cooks into gray clumps in a slow cooker, and there’s no way to drain the fat once it’s in the sauce.

Can I make cheesy taco pasta without Velveeta?

Yes. Replace the Velveeta with 1 extra cup each of shredded cheddar and Jack, toss the shredded cheese with 2 teaspoons of cornstarch, and add ½ cup of milk with the cream cheese. The sauce will taste sharper and look less glossy. It’s also more likely to break if it sits on WARM. Honestly, I keep the Velveeta. This is a dish where smooth matters more than fancy, and nothing else melts that clean.

Why did my cheese sauce turn grainy or oily?

Usually one of three things went wrong. The shredded cheese went into a bubbling sauce instead of a warm one. The cheese was pre-shredded and starch-coated. Or the beef wasn’t drained well enough, so extra fat had nowhere to go. Add the shredded cheese on WARM, a handful at a time, and most of the problem disappears.

What size slow cooker do I need for taco bowtie pasta?

A 6-quart is the minimum for the full batch, and it’ll be most of the way full. A 7-quart gives you room to stir without slopping sauce over the edge. For a 4-quart, halve the recipe.

Is slow cooker taco pasta spicy?

Mild to medium as written. The heat comes from the salsa and Rotel, so swap in mild versions of both to tone it down, or hot versions to push it up.

Can I use gluten-free bowtie pasta?

Yes, but gluten-free bowties go from firm to broken quickly. Par-boil them for about half the package time and start checking after 8 minutes in the crock. Check the label on your taco seasoning too, since some packets contain wheat.

Serving It, and What to Do With Leftovers

Something cold and crunchy next to a bowl of slow cooker cheesy taco bowtie pasta does a lot. A quick slaw of shredded cabbage, lime juice, a pinch of salt, and a little cilantro cuts right through all that cheese. Make it while the pasta finishes, and it’ll be just right by the time you sit down.

The leftovers have a second life, too. Spoon cold taco pasta onto half a flour tortilla, add a small handful of cheddar, fold it over, and press it in a dry skillet over medium heat until both sides are crisp. My family asks for those taco pasta quesadillas more than the pasta itself, which is a little insulting. But fine.
