Viral Orzo Mac and Cheese (Creamy One-Pot Recipe)

This orzo mac and cheese is rich, creamy, and ready in about 25 minutes! The orzo cooks in chicken broth and half-and-half, then gets mixed with freshly grated cheddar-Gruyère cheese for an incredibly creamy finish. Everything comes together in one skillet with no roux required, making it an easy side dish for weeknights or holiday dinners.

Why You’ll Love This Orzo Mac and Cheese

I have a thing for recreating viral mac and cheese recipes. I've made everything from the incredibly popular Tini's mac and cheese to my hearty mac and cheese lasagna. So when I was scrolling TikTok and came across this viral orzo mac and cheese from @carolbeecooks, I knew I had to make it. I'd never thought to use orzo instead of macaroni, but it looked way too good not to try. 

What I love about this version is how the orzo cooks right in the chicken broth and half-and-half, soaking up all that flavor before the cheese goes in. I toast the orzo in butter first, which adds a subtle nutty flavor. Then the cheddar-Gruyère blend melts into the pasta and creates an incredibly rich, creamy sauce with just a little kick from the cayenne.

And the best part? It's all made in one skillet with no boiling pasta separately or making a roux. The whole thing takes about 25 minutes, making it an easy side dish for weeknight dinners or a cheesy addition to your Thanksgiving spread.

Orzo Mac and Cheese Ingredients

• 2 tbsps. unsalted butter
• 1 cup uncooked orzo pasta
• 1 tsp. garlic powder
• 1 tsp. onion powder
• ½ tsp. kosher salt
• ¼ tsp. black pepper
• ¼ tsp. cayenne pepper
• 2 cups low-sodium chicken broth, plus more as needed
• ½ cup half-and-half
• 6 oz. (about 1½ cups) freshly grated cheddar-Gruyère cheese

Ingredient Notes

• Orzo pasta: I use regular uncooked orzo, which looks like rice but is actually pasta. It cooks right in the skillet, absorbing the broth and cream for an extra creamy texture.
• Cheddar-Gruyère cheese: I love this combination because cheddar adds a sharp, cheesy flavor while Gruyère melts well and adds a slightly nutty taste. I recommend freshly grating the 6 ounces cheese for the smoothest sauce.
• Chicken broth: I recommend low-sodium chicken broth so you can control the saltiness. The orzo absorbs the broth as it cooks, adding flavor without needing to boil it separately.
• Half-and-half: This makes the orzo rich and creamy without being as heavy as using all heavy cream. It also helps create a smooth cheese sauce.
• Garlic powder, onion powder, and cayenne: These simple seasonings add flavor without overpowering the cheese. I use just ¼ teaspoon of cayenne for a subtle kick, but you can leave it out if you prefer a milder mac and cheese.

How to Make Orzo Mac and Cheese

Step 1: Toast the Orzo

Melt the butter in a large skillet over medium heat. Add the uncooked orzo, garlic powder, onion powder, salt, black pepper, and cayenne pepper. Stir continuously for about 2 minutes, until the orzo is lightly golden and fragrant.

Step 2: Add the Broth and Cream

Pour the chicken broth and half-and-half into the skillet. Stir everything together, scraping up any toasted bits from the bottom of the pan. Bring the mixture to a gentle simmer.

Step 3: Cook the Orzo

Reduce the heat to medium-low and simmer for 12–15 minutes, stirring occasionally to prevent sticking. The orzo should be tender, with a little creamy liquid remaining in the skillet. If the liquid absorbs before the pasta is fully cooked, add a splash of chicken broth and continue simmering.

Step 4: Stir in the Cheese

Remove the skillet from the heat and gradually add the freshly grated cheddar-Gruyère cheese, stirring between each addition until completely melted. The remaining liquid will combine with the cheese to create a smooth, creamy sauce that coats the orzo.

Step 5: Adjust and Serve

Taste the orzo mac and cheese and adjust the seasonings if needed. If the sauce is too thick, stir in a splash of warm chicken broth until it reaches your desired consistency. Serve immediately while the cheese is melted and the orzo is warm and creamy.

My Tips for the Best Orzo Mac and Cheese

• Use a heavy-bottomed skillet. I recommend a deep, heavy-bottomed skillet that distributes heat evenly. I used a stainless steel pan. This helps prevent the orzo and cream from scorching as the liquid reduces.
• Stir more frequently toward the end. Orzo releases starch as it cooks, making the sauce naturally creamy. I like stirring more often during the last few minutes to prevent the pasta from sticking to the bottom.
• Keep the sauce slightly loose. Orzo mac and cheese thickens quickly as it cools. I recommend leaving it a little saucier than you think it needs to be so it stays creamy when served.
• Taste before adding extra salt. The chicken broth and cheese already contribute saltiness. I always taste the finished mac and cheese before adjusting the seasoning.
• Reheat with a splash of liquid. If you're reheating leftovers, add a little milk or chicken broth and warm gently over low heat, stirring until the sauce becomes creamy again.

Orzo Mac and Cheese FAQs

What is orzo mac and cheese?

Orzo mac and cheese is a creamy, cheesy pasta dish made with orzo instead of traditional elbow macaroni. Orzo is a small, rice-shaped pasta that absorbs the cooking liquid as it simmers. My version uses cheddar-Gruyère cheese, chicken broth, and half-and-half to make an extra creamy and cheesy one-pot mac and cheese.

Do you need to boil orzo before making mac and cheese?

No! For this recipe, the uncooked orzo goes directly into the skillet with butter and seasonings. It then cooks in chicken broth and half-and-half for about 12–15 minutes. There's no need to boil or drain the pasta separately.

What cheese is best for orzo mac and cheese?

I love using a cheddar-Gruyère blend because cheddar adds a sharp, cheesy flavor and Gruyère melts into a smooth, creamy sauce. Sharp cheddar, Colby Jack, or fontina are other good melting cheeses, although they'll give the dish a slightly different flavor.

Can I use milk instead of half-and-half?

Whole milk can be used for a lighter version, but the sauce won't be quite as rich or creamy. I recommend sticking with half-and-half for the best results, especially since this recipe doesn't use a traditional flour-based roux to thicken the cheese sauce.

Is orzo mac and cheese spicy?

No, the ¼ teaspoon of cayenne pepper adds a subtle kick without making the dish overly spicy. If you're making it for kids or prefer a milder flavor, you can leave out the cayenne completely.

Why is my orzo mac and cheese dry or mushy?

Orzo continues absorbing liquid as it sits, so the sauce can become too thick if the pasta cooks too long or rests before serving. Overcooking can also make the orzo mushy. Check for tenderness around 12 minutes and remove it from the heat while there's still some creamy liquid in the skillet.

Can I make orzo mac and cheese ahead of time?

Yes, but I recommend making it fresh whenever possible. Orzo absorbs more sauce as it sits, so the texture won't be quite the same after refrigeration. If you're preparing it for a holiday dinner, I'd make it shortly before serving so it's at its creamiest.

How do I store and reheat leftover orzo mac and cheese?

Store leftovers in an airtight container in the refrigerator for up to 3–4 days. To reheat, add a splash of milk or chicken broth and warm gently in a skillet over medium-low heat, stirring until creamy and heated through. You can also microwave individual portions in short intervals, stirring between each.
