How to Make Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese Recipe

Step 1: Cook the Macaroni

Begin by cooking the elbow macaroni according to the package instructions until just al dente. This ensures your pasta will hold its shape and texture throughout baking. Drain it well and set aside, ready for the creamy ingredients to come together.

Step 2: Caramelize the Onions with Balsamic Vinegar

Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the thinly sliced onions and let them cook slowly, stirring occasionally, for about 20-25 minutes. This slow cooking process transforms them into irresistibly sweet caramelized onions. Pour in the balsamic vinegar and cook for an additional 2-3 minutes, letting it soak in all that rich flavor. Remove from heat and set aside—you’ll be amazed at the depth this adds.

Step 3: Sauté the Mushrooms

In the same skillet, add the remaining tablespoon of olive oil and sauté the cremini mushrooms until they’re golden brown and tender, usually about 5-6 minutes. Don’t forget to season them with salt and freshly ground black pepper for balanced taste. Once cooked, mix the mushrooms with your caramelized onions and set aside to combine those beautiful flavors.

Step 4: Preheat the Oven

Set your oven to 350°F (175°C) so it’s ready for baking your masterpiece at the right moment.

Step 5: Prepare the Cheese Sauce

In a large saucepan, melt your butter over medium heat. Whisk in the flour and cook the roux for about a minute to remove any raw flour taste. Slowly whisk in the milk bit by bit, continuing to stir until the sauce thickens and just starts to simmer, around 5-7 minutes. This creates a velvety smooth base for the cheese to shine.

Step 6: Add the Cheeses

Turn the heat down to low and gradually stir in the shredded sharp cheddar and cheddar jack cheese. Keep stirring until all the cheese has melted into a luscious, smooth sauce. Taste and season with salt and pepper until it’s just right—creamy and packed with cheese goodness.

Step 7: Combine Everything

Fold in the cooked macaroni along with the combined caramelized onion and mushroom mixture. Make sure everything is evenly coated in that rich cheese sauce because every bite deserves that perfect balance.

Step 8: Transfer to a Baking Dish

Grease a 9×13 inch baking dish and pour the macaroni mixture evenly into it. Use a spatula to level the surface, preparing it for a beautifully crisp topping.

Step 9: Add the Crunchy Topping

Sprinkle the panko breadcrumbs evenly over the top of the macaroni and cheese. This will bake into a golden, crunchy crust that’s pure textural heaven.

Step 10: Bake to Perfection

Place the dish in your preheated oven and bake for 20-25 minutes or until the top is golden brown and bubbling, signalling all the flavors have melded into comfort food perfection.

Step 11: Let it Rest and Garnish

Remove from the oven and allow it to cool for a few minutes. This helps the sauce thicken slightly and makes serving easier. If you like, sprinkle fresh chopped parsley over the top for a lovely fresh contrast.

Make Ahead and Storage

Storing Leftovers

Store any leftover Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese Recipe in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making for even better leftovers!

Freezing

You can freeze this dish either before or after baking. Just cover tightly with foil or plastic wrap, and freeze for up to 2 months. To prevent sogginess, it helps to flash freeze uncovered for an hour first, then wrap before long-term storage.

Reheating

To reheat, thaw overnight in the fridge if frozen, then warm in a preheated oven at 350°F until bubbly and heated through. Microwaving works in a pinch but can result in uneven texture and some dryness.

FAQs

Can I use different types of mushrooms?

Absolutely! While cremini mushrooms add a nice earthy flavor, you can swap them with button mushrooms, shiitake, or even portobello for varying textures and tastes.

Is this recipe vegetarian?

Yes, it is! This version contains no meat but is packed with savory flavor from the mushrooms and caramelized onions. Just ensure your cheese is vegetarian if that’s important to you.

Can I make this recipe dairy-free?

For a dairy-free version, try substituting the butter with a plant-based alternative, use a non-dairy milk like oat or almond, and find vegan cheese options that melt well.

What’s the best way to get really creamy mac ‘n’ cheese?

Low and slow cooking of the cheese sauce is key. Don’t rush melting the cheese, and use a mix of sharp and mild cheeses for both flavor and melty texture.

Can I prepare the caramelized onions and mushrooms ahead of time?

Definitely! You can caramelize the onions and sauté the mushrooms a day or two before to save time on the day you make the full recipe. Just store them in airtight containers in the fridge.
