Creamy, spicy, and ridiculously comforting—this set-it-and-forget-it dinner is about to become your new go-to for potlucks, game-day gatherings, and every busy weeknight in between.

Ingredients You'll Need

Great mac and cheese starts with great building blocks. Below is everything you need—plus my tried-and-true shopping notes so you know exactly what to grab (and what to avoid) at the grocery store.

Boneless, skinless chicken thighs: Thighs stay juicier than breasts during the long cook time. If you only have breasts, reduce the slow-cook time by 30 minutes and check for doneness with a thermometer (165 °F/74 °C).
Buffalo wing sauce: I use Frank’s RedHot® Wings for that classic taste, but any vinegar-forward cayenne pepper sauce works. Avoid “buffalo-style” dressings; they’re too thick and can separate.
Elbow macaroni: Buy the ridged (rigate) variety; the sauce clings better. Regular elbows become mushy after hours in the slow cooker, so we’ll par-cook them later.
Sharp cheddar + pepper jack: A 2:1 ratio gives you maximum melt plus a gentle back-heat. Pre-shredded cheese is coated with cellulose and can turn gritty—grate your own for silk-smooth sauce.
Cream cheese: Full-fat, brick-style. Whipped or low-fat varieties add too much water and break under heat.
Chicken broth: Low-sodium lets you control salt. Warm it in the microwave for 30 seconds so the dairy doesn’t seize when it hits the crock.
Butter & flour: We’re making a quick roux right in the insert for extra insurance against curdling.
Ranch seasoning: One packet (about 3 Tbsp) rounds out the tang. If you prefer blue cheese, swap in 2 Tbsp crumbled blue cheese plus 1 tsp garlic powder.
Green onions & celery: Optional, but the crunch mimics the bar-snack experience and photographs beautifully.

Why This Recipe Works

One appliance: Everything—roux, chicken, pasta, sauce—happens in the slow cooker so you skip every extra pan.
Layered heat: Buffalo sauce cooks into the chicken while pepper jack sneaks in a second, mellower kick.
No curdle: A brief roux plus softened cream cheese keeps the sauce stable for hours.
Customizable: Dial the spice up or down, swap cheeses, go gluten-free—details below.
Feed a crowd: Ten generous servings make it party-perfect without doubling.
Freezer-friendly: Portion, freeze, and reheat straight from frozen for instant comfort.

How to Make Slow Cooker Buffalo Chicken Mac & Cheese

Brown the roux

Set a 6-quart (or larger) slow cooker to HIGH. Add 3 Tbsp butter; cover 5 minutes until melted. Whisk in 3 Tbsp all-purpose flour until peanut-butter colored and bubbling—about 90 seconds. This quick roux stabilizes the dairy and prevents that dreaded grainy texture.

Season the chicken

Pat 2 lb (900 g) chicken thighs dry with paper towels; moisture is the enemy of browning. Sprinkle with 1 tsp kosher salt, ½ tsp black pepper, and the ranch seasoning. Nestle the thighs directly into the roux.

Add liquids & initial cook

In a 2-cup glass measure, whisk 1 cup (240 ml) warm low-sodium chicken broth with ⅓ cup (80 ml) buffalo sauce until smooth. Pour around—not over—the chicken so you don’t wash off seasoning. Cover and cook on HIGH 1 hour 30 minutes or LOW 3 hours.

Shred & return

Transfer chicken to a plate and shred with two forks. The meat should yield easily but still be moist. Return shreds plus any juices to the crock and stir to coat with the spicy broth.

Par-cook the pasta

Meanwhile, bring a medium pot of salted water to a boil. Add 3 cups (12 oz/340 g) elbow macaroni and cook exactly 3 minutes less than package directions for al dente. Drain immediately and rinse under cold water to halt cooking. This step prevents mushy noodles during the long cheese melt.

Build the cheese sauce

Cut 8 oz (225 g) cold cream cheese into ½-inch cubes and scatter over the shredded chicken. Add 1 cup (90 g) extra-sharp cheddar and ½ cup (45 g) pepper jack. Cover 10 minutes to soften, then whisk until velvety. Fold in the par-cooked pasta plus ½ cup (120 ml) milk for pourable consistency.

Final melt & spice check

Cover and cook HIGH 15 minutes or LOW 30 minutes, until pasta is tender and sauce has thickened. Taste; stir in extra buffalo sauce 1 Tbsp at a time for more heat. The flavor intensifies as it sits, so err on the mild side if serving kids.

Serve & garnish

Switch the slow cooker to WARM. Ladle into bowls and top with remaining cheddar, sliced green onions, and finely diced celery for crunch. A drizzle of ranch or blue cheese dressing is never frowned upon.

Expert Tips

Temperature matters

Cold dairy can seize when it meets hot broth. Let cream cheese and milk sit on the counter 20 minutes before stirring in.

Thin or thick?

Sauce too tight? Stir in warm broth 2 Tbsp at a time. Too loose? Leave the lid ajar on HIGH 10 minutes to evaporate.

Spice control

Replace half the buffalo sauce with an equal amount of plain tomato sauce for kiddos, then pass extra hot sauce at the table.

Keep it warm

The KEEP WARM setting is your friend for parties. Stir every 20 minutes to prevent a skin forming on top.

Cheese swap

For ultra-gooey texture, substitute 25 % of the cheddar with white American cheese slices; they melt like a dream.

Double batch

You can double everything in an 8-quart cooker. Increase final melt time by 10 minutes and stir halfway.

Variations to Try

Vegetarian: Swap chicken for two 15-oz cans of chickpeas, drained. Reduce initial cook time to 45 minutes on HIGH.
Gluten-free: Use gluten-free elbows and replace flour with 2 tsp cornstarch whisked into the broth.
Smoky bacon: Stir in ½ cup cooked, crumbled bacon just before serving for a smoky note that pairs brilliantly with buffalo.
Extra veg: Fold in 1 cup steamed broccoli florets or roasted cauliflower during the final melt for a sneaky nutrition boost.
Mac & cheese pizza: Spread leftovers in a buttered 9-inch pie plate, top with mozzarella, and bake 10 minutes at 425 °F for a cheesy pizza crust.

Storage Tips

Refrigerate: Cool completely, transfer to airtight containers, and refrigerate up to 4 days. Reheat gently with a splash of broth or milk on the stovetop or microwave (50 % power) to loosen.

Freeze: Portion into freezer-safe zip bags, press out air, label, and freeze up to 3 months. Thaw overnight in the fridge, then reheat slowly—high heat can break the sauce.

Make-ahead: The chicken and sauce base (through Step 4) can be prepared up to 2 days in advance. Store separately from the par-cooked pasta; combine and finish Step 6 when ready to serve.

Frequently Asked Questions

Yes. Add 30 minutes to the initial cook time on HIGH. Be sure the internal temp reaches 165 °F before shredding.

Either the dairy was too cold or the cooker was too hot. Whisk in warm milk a little at a time; an immersion blender also smooths things out.

You can, but results vary by cooker. Add ½ cup extra broth and stir after 20 minutes to prevent clumping. Texture won’t be quite as al-dente.

Replace up to half the buffalo sauce with plain tomato sauce and use Monterey jack instead of pepper jack. You can also stir in a spoonful of sour cream just before serving.

Traditional elbow pasta is high-carb. Substitute cooked cauliflower florets or shirataki macaroni and reduce broth by ¼ cup.

It will fit, but you’ll need to stir more often during the final melt to ensure even heating. An 8-quart model is better for doubles.
