Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese Ingredients
For the Macaroni
• Elbow Macaroni – The classic choice for this dish, holding each creamy bite. Substitute with whole grain for added nutrition.
For the Sauté
• Olive Oil – Ideal for sautéing ingredients, enhancing flavor; extra-virgin is best, but feel free to use any neutral oil.
• Onions – Caramelized to impart sweetness and depth; shallots can be used if you prefer a milder onion flavor.
• Balsamic Vinegar – This key ingredient adds a tangy sweetness to the mix; red wine vinegar works as a solid alternative.
• Cremini Mushrooms – Earthy and flavorful, they complement the cheese beautifully; try portobello or shiitake mushrooms for variety.
For the Cheese Sauce
• Unsalted Butter – Forms a rich roux for the sauce; using vegan butter makes it suitable for a dairy-free version.
• All-Purpose Flour – Essential for thickening the cheese sauce; a gluten-free blend can also be utilized.
• Milk – Creates the creamy base; feel free to switch to almond or oat milk for a non-dairy option.
• Sharp Cheddar Cheese – Offers rich flavor and creaminess; mixing with gouda adds an extra touch of depth.
• Cheddar Jack Cheese – This cheese contributes a melty texture; substitute with a similar cheese blend if needed.
• Salt and Pepper – Vital for enhancing flavor; adjust amounts according to your taste preferences.
For the Topping
• Panko Breadcrumbs – For that perfect crunchy layer on top—regular breadcrumbs can work in a pinch if necessary.
• Fresh Parsley – Optional, but adds a lovely pop of color and freshness to the dish.

Step‑by‑Step Instructions for Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese
Step 1: Cook the Macaroni
Begin by boiling a large pot of salted water over high heat. Once the water is at a rolling boil, add the elbow macaroni and cook according to package instructions until al dente, about 8-10 minutes. Drain the pasta in a colander and set aside, ensuring you save a small cup of pasta water for later if needed.
Step 2: Caramelize the Onions
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the sliced onions and stir frequently, allowing them to cook gently for about 20-25 minutes. Keep an eye on them, adjusting the heat as necessary, until they’re golden brown and caramelized. Add the balsamic vinegar, stir well, then set aside the mixture to combine flavors.
Step 3: Sauté the Mushrooms
In the same skillet that you used for the onions, add the remaining olive oil and heat over medium-high. Once hot, toss in the sliced cremini mushrooms and sauté them for 5-6 minutes until they are tender and lightly browned. Season with salt and pepper, then mix them with the caramelized onions, allowing the earthy flavors to meld.
Step 4: Preheat the Oven
While the vegetables cook, preheat your oven to 350°F (175°C). This temperature ensures that when we assemble the Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese, it will bake evenly and form a delectable, golden crust on top.
Step 5: Make the Cheese Sauce
In a saucepan, melt 4 tablespoons of unsalted butter over medium heat. Once melted, whisk in 1/4 cup of all-purpose flour, cooking for about 1 minute to form a roux. Gradually whisk in 3 cups of milk, continuing to stir until the mixture thickens, approximately 5-7 minutes. You’ll know it’s ready when it coats the back of a spoon.
Step 6: Incorporate the Cheeses
Remove the saucepan from heat and stir in 2 cups of sharp cheddar cheese and 1 cup of cheddar jack cheese. Mix until the cheeses are completely melted and the sauce is smooth. This step is where the creamy base for your Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese comes together, creating a rich texture.
Step 7: Combine Pasta and Sauce
Take the drained macaroni and fold it into the cheese sauce gently, ensuring every piece is coated. Then, mix in the caramelized onion and mushroom mixture from the skillet, allowing all the flavors to blend beautifully into the comforting pasta.
Step 8: Transfer to Baking Dish
Pour the entire mac and cheese mixture into a greased 9×13-inch baking dish. Spread it out evenly using a spatula, taking care to ensure the topping will crisp up nicely when baked.
Step 9: Add Topping and Bake
Sprinkle a generous layer of panko breadcrumbs over the top of the mac and cheese for added crunch. Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbling.
Step 10: Let Rest and Serve
Once baked, remove the Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese from the oven and let it rest for about 5-10 minutes before serving. This resting time allows the dish to set up a bit, making it easier to serve. If desired, garnish with freshly chopped parsley for a pop of color!

Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese Recipe FAQs
What type of onions should I use for caramelizing?
I recommend using yellow onions for their perfect balance of sweetness and flavor. Their natural sugars caramelize beautifully, creating that rich, sweet taste in the dish. If you prefer a milder flavor, shallots are a great alternative.
How long can I store leftovers of this mac ‘n’ cheese?
Absolutely! You can store leftovers in an airtight container for up to 3 days in the fridge. Just make sure it’s cooled completely before sealing to keep it fresh and delicious for your next meal.
Can I freeze Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese?
Yes, you can! If you want to enjoy this dish later, freeze it in a freezer-safe container for up to 2 months. For reheating, thaw overnight in the fridge, then warm it in the oven at 350°F (175°C) for about 20-25 minutes, adding a splash of milk to restore creaminess.
Why is my cheese sauce clumpy?
The key is to whisk continuously while gradually adding the milk to avoid clumps. If it does clump, gently return the saucepan to low heat, whisk vigorously, and try adding a little extra milk to smooth it out. Keeping the heat gentle helps too, as high heat can change the texture of the cheese.
Is this recipe suitable for vegans or those with dietary restrictions?
Very! To make this Balsamic Caramelized Onion Mushroom Mac ‘n’ Cheese vegan, you can substitute dairy products with plant-based alternatives. Use vegan butter, almond or oat milk, and a blend of vegan cheeses. Just double-check the panko breadcrumbs to ensure they are also vegan-friendly.
What can I use instead of panko breadcrumbs?
If you don’t have panko on hand, regular breadcrumbs can work in a pinch. To replicate the desired crunch, consider toasting them lightly in a pan with a bit of olive oil before adding them as a topping for that extra crispiness!
