Ingredient Notes
Simple pantry and fridge staples are all that is needed for the recipe. Here's what you'll need (full amounts are in the recipe card below):
- Orzo - The star of this recipe. Orzo is shaped like a grain of rice, but is actually pasta. Cook it to al dente to keep your orzo mac and cheese tender, not mushy.
- Liquid - A mix of milk and water helps the orzo cook while creating that base for a creamy orzo cheese sauce. I use 1% as that's what we drink at home.
- Seasonings - Mustard, garlic powder, and salt add depth. Mustard is the secret weapon in cheese sauces: it's acidity cuts through the richness and keeps things smooth.
- Cheese - Sharp cheddar brings a ton of flavor and tons of cheesy goodness. Want to mix it up? Gruyère, Fontina, or Monterey Jack all melt beautifully. A combo of two or three cheeses is also great!
How to Make Orzo Mac & Cheese
This stovetop mac and cheese recipe comes together in one pot and three quick steps:
Step 1: Toast the orzo (optional but worth it). Melt butter in a saucepan and sauté the orzo for a couple minutes. A few pieces will start to brown, and you'll smell a nutty aroma. This adds flavor!
Step 2: Add the liquid & cook - Stir in water, milk, mustard, salt and garlic powder. Bring the mixture to a light simmer and cook just until the orzo is tender. Check the box instructions and start checking a minute or 2 before. There will be liquid left at this point: this will become the cheese sauce!
Step 3: Add the cheese - Turn off the heat and add the cheddar cheese. Gently stir until the cheese is melted and combined. Add the parmesan. Season with some black pepper and additional salt, if needed.
Step 4: Let it sit - This is the hardest part. Let the cheesy orzo sit off the heat for 5 minutes. The orzo will continue to soak up the extra liquid and create the perfect creamy texture.
Quick Tip: Grate your own cheese for the best melting results!
Serving Ideas
This orzo mac and cheese works as both a main and a side:
Main dish: Serve with steamed veggies or a simple green salad.
Side dish: Serve alongside steak, chicken, pork chops, or baked ham for classic comfort food vibes.
Veggie boost: Stir in cooked broccoli or peas to get those veggies in.
How to Store & Reheat Leftovers
Fridge: Cool completely, then store in an airtight container for 3-4 days. For big batches, divide into smaller containers so they cool faster and reheat more evenly (good practice for food safety!).
Freezer: Orzo is softer than other noodles, but you can freeze it. Store in freezer-safe containers for up to 2 months. Thaw overnight in the fridge, then reheat gently.
Reheating: Reheat on the stovetop with a splash of milk to avoid a gummy texture. You can also reheat in the microwave with a splash of milk.

📖 Recipe
One-Pot Orzo Mac & Cheese
Ingredients
Method
- In a stockpot or skillet melt butter over medium heat. Add orzo and cook until orzo just starts to toast, about 2-3 minutes .1 tbsp. butter, 1 cup orzo
- Add water, milk, mustard, salt and garlic powder. Stir and bring to a simmer. Cook for 7-8 minutes until orzo is just tender (there will be liquid left).2 cups water, 1 cup milk, 1 tsp. yellow mustard, 1 tsp. salt , 1 tsp. garlic powder
- Turn off the heat and add the cheddar cheese. Stir until cheese is melted and combined. Do the same with the parmesan cheese. Season with additional salt & black pepper, if desired.2 cups sharp cheddar cheese, ¼ cup parmesan cheese
- Let orzo sit off the heat for 5 minutes before serving. This allows the orzo to absorb more of the liquid to create the perfect creamy sauce.
Notes
- Start checking the orzo 1-2 minutes fewer than the package instructions. It will continue to cook just enough when you finish it with the cheese. This prevents the orzo from becoming mushy.
- Be sure to lower the heat before adding the cheese. Slow melting = a smoother sauce. Grating your own cheese is also crucial as pre-shredded contains anti-caking agents that will make your sauce grainy.
- To reheat leftovers, add a splash of milk and stir on the stove until heated through.
