Ingredients
Main Ingredients List
- 8 oz elbow macaroni

- 1 cup sharp white cheddar cheese, shredded
- 1 cup whole milk

This dish starts with elbow macaroni. It holds the cheese and sauce well. Aim for quality in your pasta. Next, we need white cheddar cheese. The blend of two types adds depth. Sharp white cheddar brings a tangy flavor.
Dairy components like whole milk and heavy cream create creaminess. They help the cheese melt smoothly. Unsalted butter brings richness while caramelizing the onions.
Onions are key for sweetness. Slice them thin for even cooking. Garlic adds a punch of flavor.
Seasonings like Dijon mustard, salt, and pepper enhance the dish. Add cayenne pepper for a spicy kick if you like.
Finally, breadcrumbs create a crunchy topping. While not required, they add texture. Fresh parsley gives a pop of color and freshness.
Gather these ingredients before you start. This recipe is simple and satisfying. Each ingredient plays a role in making this mac and cheese a delight.

Step-by-Step Instructions
Cooking the Pasta
To start, fill a large pot with water and add salt. Bring it to a boil. Once boiling, add 8 oz of elbow macaroni. Cook it according to the package instructions until it's al dente, which means it's firm but not hard. This usually takes about 7 to 9 minutes. Drain the pasta and set it aside in a large bowl.
Caramelizing the Onions
Next, let's caramelize the onions. In a large skillet, melt 1 tablespoon of unsalted butter over medium heat. Add 2 large onions that you sliced thinly. Stir them often to prevent burning. Cook for about 15 to 20 minutes until they turn golden brown and soft. Add 2 cloves of minced garlic in the last 2 minutes of cooking to get that nice garlic flavor. Once done, remove the skillet from the heat.
Making the Cheese Sauce
Now, we’ll make the cheese sauce. In a saucepan over medium heat, combine 1 cup of whole milk and 1 cup of heavy cream. Stir well and heat it until it’s warm but not boiling. Gradually add 2 cups of shredded white cheddar cheese while stirring constantly. This helps the cheese melt smoothly. Mix in 1 teaspoon of Dijon mustard, 1 teaspoon of salt, ½ teaspoon of black pepper, and ¼ teaspoon of cayenne pepper if you want some heat.
Combining All Ingredients
After making the cheese sauce, it’s time to mix everything together. Pour the cheese sauce over the cooked pasta in the large bowl. Stir until the pasta is well coated with the sauce. Now, gently fold in the caramelized onions to add sweetness and depth to the dish.
Baking Instructions (Optional)
If you like a baked version, preheat your oven to 350°F (175°C). Transfer your macaroni and cheese mixture into a greased baking dish. Sprinkle ¼ cup of breadcrumbs evenly on top for a crunchy texture. Bake it in the preheated oven for about 20 minutes, or until it’s golden and bubbly.
Serving Suggestions
Once baked, remove it from the oven. Let it sit for a few minutes to cool down. Before serving, garnish with chopped fresh parsley for a pop of color and flavor. Enjoy your creamy white cheddar mac n cheese with caramelized onions!
Tips & Tricks
Perfecting Caramelization
To get the best flavor from your onions, cook them slowly. Keep the heat at medium-low. This way, they turn golden brown and sweet. Stir the onions every few minutes. This helps them cook evenly. If you leave them alone, some may burn, while others stay raw. Don't rush this step; good caramelization takes time.
Achieving Creamy Cheese Sauce
Use low heat when melting cheese. This helps it melt without clumping. Start with milk and cream in a saucepan. Stir in your cheeses a little at a time. This makes a smooth sauce. If you want extra creaminess, try adding cream cheese or sour cream. These options blend well and enhance the flavor.
Enhancing Flavor
Add spices to kick up the taste. A bit of salt and black pepper helps. For a spicy touch, use cayenne pepper. Just a little goes a long way. If you like it hot, feel free to add more! You can also mix in a pinch of garlic powder or smoked paprika for depth. These little changes make a big difference!
Pro Tips
- Use Fresh Cheese: Freshly shredded cheese melts better than pre-shredded cheese, which often contains anti-caking agents.
- Perfect Pasta Texture: Cook the pasta just to al dente; it will continue to cook in the oven if baking, preventing mushy mac and cheese.
- Enhance Flavor: For an extra depth of flavor, consider adding a splash of white wine to the cheese sauce while it simmers.
- Breadcrumb Topping: For added texture, mix some grated Parmesan cheese with the breadcrumbs before sprinkling them on top for baking.
