Kimchi Mac and Cheese

The first time my Korean roommate saw me making boxed mac and cheese, she gently suggested we try adding her homemade kimchi. I was skeptical that fermented cabbage could improve my comfort food staple, but one bite of that bubbling, spicy-cheesy pan completely changed my understanding of what mac and cheese could be. Now I keep an extra jar of kimchi in the fridge specifically for those nights when regular cheese sauce just won not cut it.

Last winter during a particularly brutal cold snap, I made a massive batch for my friend who swore she hated spicy food. She ended up scraping the dish clean and asking for the recipe before she even finished her first serving. Something magical happens when the kimchi gets slightly caramelized in the oven, creating these little pockets of concentrated umami that make every bite exciting.

Ingredients

• 300 g elbow macaroni: The curves catch extra cheese sauce and kimchi bits perfectly
• 2 tbsp unsalted butter: Forms the base of your roux, creating that silky cheese sauce texture
• 2 tbsp all-purpose flour: Essential for thickening the sauce without making it heavy
• 500 ml whole milk: Full fat makes a noticeably creamier sauce worth every calorie
• 150 g sharp cheddar cheese: Mature cheddar brings the bold flavor needed to stand up to kimchi
• 50 g mozzarella cheese: Creates those gorgeous cheese pulls we all secretly love
• 1 tsp Dijon mustard: The secret ingredient that amplifies cheese flavor without adding mustard taste
• 200 g kimchi, well-drained: Excess liquid will make your sauce separate, so squeeze it gently
• 1 tbsp kimchi juice: Adds essential fermentation flavor without overwhelming the dish
• 2 spring onions: Fresh brightness that bridges the gap between cheese and spice
• 1 tbsp gochujang: Optional but highly recommended for authentic Korean depth
• 30 g panko breadcrumbs: Creates the crispy topping that contrasts beautifully with creamy pasta
• 1 tbsp sesame seeds: Nutty crunch that makes the dish look restaurant-worthy

Instructions

Preheat and prep:

Heat your oven to 200°C and give a medium baking dish a quick coating of butter or oil.

Cook pasta:

Boil macaroni until barely al dente since it will cook more in the oven later.

Make roux:

Melt butter over medium heat, whisk in flour, and cook for one minute until it smells nutty.

Add milk:

Pour in milk gradually while whisking constantly to prevent lumps.

Thicken sauce:

Simmer for 4-5 minutes until the sauce coats the back of a spoon.

Add cheese:

Reduce heat and stir in cheddar, mozzarella, mustard, pepper, and salt until melted.

Combine everything:

Fold in pasta, kimchi, kimchi juice, spring onions, and gochujang.

Top and bake:

Sprinkle with panko mixed with butter and sesame seeds, then bake 15 minutes.

Rest before serving:

Let it sit for 5 minutes so the sauce can set slightly.

This dish has become my go-to for potlucks because it is impossible to stop eating once you start. I once made it for a Super Bowl party and people ignored the wings to crowd around the mac and cheese, asking what made it so addictive.

Choosing Your Kimchi

Fermented longer tastes better here since the funkier flavor stands up to all that rich cheese. I have found that kimchi straight from the refrigerator section works better than shelf-stable versions. The texture should still have some crunch, not be mushy.

Making It Ahead

You can assemble everything up to 24 hours in advance and store it covered in the refrigerator. Add an extra 10 minutes to the baking time if cooking from cold. The panko topping goes on just before baking to keep it crispy.

Serving Suggestions

This dish is rich enough to stand alone as a main, but a simple green salad with citrus vinaigrette cuts through the heaviness beautifully. I have also served it alongside grilled Korean short ribs for an over-the-top feast.

• Cold beer or dry Riesling balances the spice perfectly
• Extra chopped kimchi on top adds fresh crunch
• A drizzle of sesame oil right before serving wakes up all the flavors

Recipe FAQs

→ Can I make this ahead of time?

Yes, assemble the dish up to 24 hours in advance and refrigerate. Add 10-15 minutes to baking time if cooking from cold. For best results, add the panko topping just before baking.

→ What type of kimchi works best?

Use well-fermented, mature kimchi for the deepest flavor. Drain thoroughly and chop into bite-sized pieces. The kimchi juice adds essential tanginess, so don't skip it.

→ Can I freeze leftovers?

Portion cooled leftovers into airtight containers and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat at 180°C (350°F) until hot throughout. The topping may lose some crispness.

→ How can I make it spicier?

Add the optional gochujang for extra depth and heat. You can also include sliced fresh chilies in the mixture or use a particularly aged kimchi. Start with 1 teaspoon gochujang and adjust to taste.

→ What goes well with this dish?

Serve alongside a crisp green salad with Asian-inspired dressing. Pair with chilled Riesling, dry cider, or cold lager to complement the rich, spicy flavors. Grilled vegetables or roasted broccoli also make excellent sides.
