Colorful Gluten Free Macaroni Salad

Here is my favorite gluten-free macaroni salad recipe, with tender gluten-free pasta, crunchy veggies like bell pepper, celery, and carrots, and a creamy dressing made with mayo, mustard, and a hint of smoked paprika.

This macaroni salad is perfect for summer potlucks and barbecues. I love that it’s easy to throw together and everyone can enjoy it, whether they’re gluten-free or not. Plus, it tastes even better the next day after all those flavors have had time to hang out together in the fridge.

What Kind of Gluten-Free Pasta Should I Use?

For this macaroni salad, you’ll want to pick a gluten-free pasta that holds up well when mixed with mayo and veggies. Brands made from rice flour or a rice-corn blend tend to work really well because they don’t get mushy as easily as some other varieties. If you can find one made with chickpea or lentil flour, those are great too and add a bit of extra protein to your salad. Just make sure to cook your pasta al dente and rinse it with cold water right after draining – this stops the cooking process and helps prevent that gummy texture that gluten-free pasta can sometimes get.

Options for Substitutions

This macaroni salad is easy to customize based on what you have in your kitchen:

• Gluten-free elbow macaroni: You can use any gluten-free pasta shape you like – shells, rotini, or penne all work great. Just stick with gluten-free pasta if you need to keep it celiac-friendly.
• Vegan soy-free mayo: Regular mayo works perfectly if you’re not following a vegan diet. You can also use Greek yogurt or a mix of half mayo and half Greek yogurt for a tangier, lighter version.
• Red bell pepper: Green, yellow, or orange bell peppers are all fair game. You can also mix colors for a more colorful salad.
• White vinegar: Apple cider vinegar or red wine vinegar make good substitutes and add a slightly different flavor profile.
• Dijon mustard: Yellow mustard works in a pinch, though it’ll give you a milder, less tangy taste. Use the same amount.
• Red onion: White or yellow onion can replace red onion, or try green onions for a milder onion flavor.

Watch Out for These Mistakes While Cooking

The biggest mistake with gluten-free pasta is overcooking it, which can turn your macaroni into mush – start checking for doneness a minute or two before the package directions suggest, since gluten-free noodles can go from perfect to mushy quickly.

Skipping the cooling step is another common error that leads to a warm, soupy mess, so rinse your cooked pasta under cold water and let it cool completely before mixing with the mayo-based dressing.

To keep your salad from becoming watery after a few hours, make sure to drain your vegetables well if you’ve rinsed them, and consider adding the dressing just before serving if you’re making it ahead of time.

For extra flavor, try toasting your diced vegetables in a dry pan for a few minutes before adding them, which brings out their natural sweetness and adds a nice depth to the salad.

What to Serve With Gluten Free Macaroni Salad?

Macaroni salad is the perfect side dish for any backyard barbecue or picnic, so I love pairing it with grilled burgers, hot dogs, or chicken. It also goes really well alongside pulled pork sandwiches or ribs if you’re doing a full cookout spread. For a lighter meal, try serving it with grilled fish or shrimp skewers, which balance out the creamy pasta nicely. You can also round out your plate with some corn on the cob, coleslaw, or baked beans for a classic summer meal that everyone will enjoy.

Storage Instructions

Store: This macaroni salad actually gets better after sitting in the fridge for a few hours, so it’s perfect for making ahead. Keep it in an airtight container in the refrigerator for up to 4 days. The flavors really meld together nicely overnight, making it an ideal potluck or picnic dish.

Refresh: If your salad seems a bit dry after a day or two, just stir in a tablespoon or two of extra mayo to bring it back to life. The pasta tends to absorb the dressing as it sits, so don’t worry if you need to add a little more moisture before serving.

• Calories: 1200-1400
• Protein: 18-24 g
• Fat: 58-70 g
• Carbohydrates: 160-180 g

Ingredients

For the salad:

• 8 oz gluten-free macaroni (Barilla recommended)
• 1 cup red bell pepper, finely diced
• 1 cup celery, chopped
• 1 cup carrots, shredded
• 2/3 cup red onion, finely minced

For the dressing:

• 1 1/4 cups mayo
• 1 1/2 tbsp white vinegar
• 1 tbsp yellow mustard
• 1/2 tsp sugar
• 1/2 tsp smoked paprika
• 1/2 tsp black pepper

Step 1: Prepare the Vegetables

• 1 cup red bell pepper, finely diced
• 1 cup celery, chopped
• 1 cup carrots, shredded
• 2/3 cup red onion, finely minced

While the pasta water comes to a boil, prepare all your vegetables to save time during assembly.

Finely dice the red bell pepper, chop the celery into small pieces, shred the carrots, and mince the red onion as finely as possible—this ensures even distribution throughout the salad and prevents any one vegetable from dominating a bite.

Set all the prepared vegetables aside in a large mixing bowl.

Step 2: Cook the Gluten-Free Pasta

• 8 oz gluten-free macaroni

Bring a large pot of salted water to a boil and add the gluten-free macaroni.

Cook for 9-10 minutes until tender but still holding its shape—gluten-free pasta can become mushy quickly, so don’t overcook it.

Drain the pasta in a colander and spread it on a baking sheet or large plate to cool to room temperature.

I like to let it cool completely before mixing with the creamy dressing so the mayo doesn’t warm up and become too thin.

Step 3: Make the Creamy Dressing Base

• 1 1/4 cups mayo
• 1 1/2 tbsp white vinegar
• 1 tbsp yellow mustard
• 1/2 tsp sugar
• 1/2 tsp smoked paprika
• 1/2 tsp black pepper

In a small bowl, whisk together the mayo, white vinegar, yellow mustard, sugar, smoked paprika, and black pepper until completely smooth and well combined.

The vinegar and mustard add brightness and depth to the mayo-based dressing, while the smoked paprika gives it a subtle smoky note that elevates this classic salad beyond typical versions.

Taste and adjust seasonings as needed—remember that the vegetables will add their own flavors, so don’t oversalt.

Step 4: Combine and Coat Everything

• cooled cooked pasta from Step 2
• prepared vegetables from Step 1
• creamy dressing from Step 3

Add the cooled cooked pasta from Step 2 to the bowl with the prepared vegetables from Step 1.

Pour the dressing from Step 3 over the pasta and vegetables, then fold everything together gently but thoroughly until every piece is coated with the creamy dressing.

I find that using a rubber spatula and folding rather than stirring aggressively helps keep the pasta intact and prevents it from breaking apart.

Let the salad sit in the refrigerator for at least 30 minutes to allow the flavors to meld together.
