Introduction
Classic mac and cheese gets a seriously indulgent upgrade in this crockpot shrimp mac and cheese recipe. Tender pasta simmers in a rich, cheesy sauce right in the slow cooker, and juicy shrimp gets stirred in near the end, turning a comfort food classic into something hearty enough to call dinner.
I love this one because it takes something everyone already loves and makes it feel a little more special without a ton of extra effort. The pasta cooks right in the crockpot alongside the cheese sauce, so there’s no separate pot to boil, and by the time the shrimp is added, the whole kitchen smells like the coziest kind of comfort food.
Serve it as a filling main dish on its own, or pair it with a simple salad if you want to round things out. However you serve it, this crockpot shrimp mac and cheese is the kind of dinner that makes everyone go back for seconds.

Ingredient Notes
Small pasta shapes like elbow macaroni, shells, or cavatappi work best here since they cook evenly in the crockpot and hold onto the cheese sauce well. Larger or longer pasta shapes tend to cook unevenly in a slow cooker, so it’s worth sticking with something compact.
A combination of sharp cheddar and a melty cheese like Monterey Jack or Colby gives this dish the best balance of flavor and smooth texture, since sharp cheddar alone can sometimes turn slightly grainy when melted for a long time. Using freshly shredded cheese rather than the pre-shredded, bagged kind also helps, since the anti-caking coating on bagged cheese can prevent it from melting as smoothly.
For the shrimp, medium to large peeled and deveined shrimp work best, and just like other crockpot shrimp dishes, timing matters most here. Stir it in only during the final 15–20 minutes of cooking, since shrimp cooks quickly and will turn tough and rubbery if left in the slow cooker’s steady heat for the full cook time.
🧀 Crockpot Shrimp Mac and Cheese Recipe
Prep Time: 15 minutes | Cook Time: 2–2.5 hours (low) | Total Time: about 2 hours 45 minutes Servings: 6
Ingredients
For the Mac and Cheese:
- 2 cups elbow macaroni or small shell pasta, uncooked
- 3 cups whole milk
- 1 cup chicken broth
- 4 tbsp unsalted butter, cubed
- 1 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp salt, plus more to taste
- 1/4 tsp black pepper
- 2 cups shredded sharp cheddar cheese
- 1 cup shredded Monterey Jack cheese
- 4 oz cream cheese, cubed and softened
For the Shrimp:
- 1.5 lbs medium to large shrimp, peeled and deveined
- 1 tbsp olive oil
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/2 tsp smoked paprika
For Topping:
- 1/2 cup extra shredded cheddar cheese
- 2 tbsp chopped fresh parsley or chives
Instructions
Step 1: Add the pasta and liquid to the crockpot. Add the uncooked pasta, milk, chicken broth, cubed butter, garlic powder, onion powder, salt, and pepper directly to the crockpot. Stir well to combine, making sure the pasta is mostly submerged in the liquid.
Step 2: Cook on low. Cover and cook on low for 2 to 2.5 hours, stirring every 30–45 minutes, until the pasta is tender and most of the liquid has been absorbed. Tip: stirring periodically here is important — it prevents the pasta from sticking together or settling unevenly at the bottom of the crockpot.
Step 3: Season and sear the shrimp. While the pasta cooks, toss the shrimp with olive oil, salt, pepper, and smoked paprika. About 20 minutes before the pasta finishes, heat a skillet over medium-high heat and sear the shrimp for about 1–2 minutes per side, until just pink and opaque.
Step 4: Stir in the cheese. Once the pasta is tender, stir in the shredded cheddar, Monterey Jack, and cream cheese, mixing well until fully melted and smooth. Tip: add the cheese gradually and stir thoroughly between additions — dumping it all in at once can cause it to clump instead of melting evenly.
Step 5: Adjust the consistency. If the mac and cheese seems too thick after the cheese is stirred in, add a splash of extra milk to loosen it to your preferred consistency. Keep in mind that it will continue to thicken slightly as it sits, so aim for a slightly looser texture than you want the final dish to be.
Step 6: Add the shrimp. Gently fold the seared shrimp into the mac and cheese, being careful not to break up the pasta too much. Cover and cook on low for another 10–15 minutes, just until everything is heated through and the shrimp is fully incorporated.
Step 7: Taste and adjust. Give the dish a final taste and adjust the salt, pepper, or garlic powder as needed to get the balance right. If you’d like a little extra richness, stir in an additional tablespoon or two of butter at this point.
Step 8: Top and serve. Sprinkle the top with the extra shredded cheddar cheese and let it sit, covered, for a few minutes until melted. Garnish with chopped fresh parsley or chives and serve warm, straight from the crockpot.
Recipe Notes
- Check the pasta a bit earlier than the suggested time if your crockpot tends to run hot, since overcooked pasta can turn mushy.
- Freshly shredded cheese melts far more smoothly than the pre-shredded, bagged kind, so it’s worth shredding your own for the best texture.
- This dish also works well with cooked, crumbled bacon stirred in alongside the shrimp for extra flavor and texture.

Storage & Reheating
Leftovers will keep in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop over low heat or in the microwave in short bursts, stirring in a splash of milk to loosen the sauce, which tends to thicken significantly once chilled.
This dish isn’t a great candidate for freezing, since both the pasta and the cheese sauce change texture noticeably after thawing, often turning grainy or mushy. If you’d like to prep ahead, you can measure out the dry ingredients and chop the shrimp a day in advance to make assembly quicker.
Budget Note
This recipe costs about $3–4 per serving, with shrimp and cheese being the main cost drivers, though it’s still generally more affordable than ordering a similar dish at a restaurant. To stretch it further, use a bit less shrimp and add extra pasta or a can of drained corn to bulk up the dish without significantly increasing the cost.
Variations
Healthier/Lighter Version: Use reduced-fat cheese and milk to lighten up the sauce while still keeping it creamy, and reduce the butter slightly as well. The texture stays fairly similar, so this swap doesn’t drastically change the eating experience.
Spicy Version: Stir in a diced jalapeño or a can of diced tomatoes with green chilies (Rotel) along with the cheese for a spicy, Southwestern-style twist. A pinch of cayenne pepper also works well if you’d like heat without extra texture.
Bacon Shrimp Mac Version: Stir in 4–5 slices of cooked, crumbled bacon along with the shrimp for extra richness and a smoky, salty contrast. This variation makes the dish feel even more indulgent for a special dinner or gathering.
Meal-Prep Friendly: Make a full batch and portion it into containers for easy lunches throughout the week. Reheat gently on the stove or in short microwave bursts, stirring in a splash of milk to keep the sauce smooth and the shrimp from turning tough.
Frequently Asked Questions
Can I make this ahead of time? You can chop the shrimp and measure out the dry ingredients a day in advance, but it’s best to actually cook the pasta and cheese sauce fresh for the best texture. Cooked leftovers do reheat reasonably well, so making a full batch ahead and reheating portions throughout the week also works.
Why is my pasta mushy? This usually happens from cooking it too long or on too high a heat setting. Stick to low heat, check the pasta a bit early if your crockpot tends to run hot, and remove it from heat as soon as it’s tender rather than letting it continue cooking.
Can I use a different pasta shape? Yes — shells, cavatappi, or any small, compact pasta shape will work well in place of elbow macaroni. Avoid long noodles like spaghetti or fettuccine, since they don’t cook as evenly in a slow cooker.
Can I use frozen shrimp? Yes — just make sure it’s fully thawed and patted dry before searing, since excess moisture can prevent a good sear and may thin out the cheese sauce slightly. Thaw it overnight in the fridge or under cold running water if you’re short on time.
What should I serve with crockpot shrimp mac and cheese? A simple green salad or steamed vegetables like broccoli or green beans pair nicely to balance out the richness of the dish. Garlic bread is also a natural addition if you want to round out the meal even further.
