Kimchi Mac and Cheese

The first time I tasted kimchi and cheese together, I was skeptical about the combination, but that first bite completely changed my mind. The tangy fermented spice cuts through the rich creaminess in ways I never expected. Now it is the comfort food I crave on rainy Tuesdays or whenever I need something that feels like a warm hug with a kick.

I made this for a dinner party last winter and watched my guests go quiet after their first bites. Someone actually asked if there was a secret ingredient, and I just smiled and pointed to the jar of kimchi on the counter. Since then, it has become the most requested dish at every gathering.

Ingredients

• 300 g elbow macaroni: The curves catch the sauce perfectly and feel nostalgic
• 2 tbsp unsalted butter: Creates the base for your roux and builds that creamy foundation
• 2 tbsp all-purpose flour: Essential for thickening the cheese sauce into silky perfection
• 500 ml whole milk: Full fat makes all the difference for richness and body
• 150 g sharp cheddar cheese, shredded: The bold sharpness stands up to the kimchi flavor
• 50 g mozzarella cheese, shredded: Adds that irresistible stretch and melt factor
• 1 tsp Dijon mustard: A secret ingredient that enhances the cheesy flavor without tasting mustardy
• ¼ tsp ground black pepper: Adds subtle warmth that complements the spice
• ½ tsp salt: Balances and brings all flavors together
• 200 g kimchi, chopped and well-drained: The star ingredient, so squeeze out excess liquid to prevent a watery dish
• 1 tbsp kimchi juice: Pure fermented flavor that infuses the whole dish
• 2 spring onions, finely sliced: Fresh bite and beautiful color contrast
• 1 tbsp gochujang: Optional but recommended for that extra layer of complexity and heat
• 30 g panko breadcrumbs: Creates the most satisfying crispy golden topping
• 1 tbsp unsalted butter, melted: Helps the breadcrumbs turn perfectly golden brown
• 1 tbsp sesame seeds: Nutty crunch that screams Korean-inspired comfort

Instructions

Get your oven ready:

Preheat to 200°C and grease your baking dish so nothing sticks later

Cook the pasta:

Boil macaroni until just al dente, then drain because it will cook more in the oven

Make the roux:

Melt butter over medium heat, whisk in flour for one minute until bubbly and fragrant

Create the cheese sauce:

Slowly pour in milk while whisking constantly, let it thicken for about five minutes

Add the cheeses:

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

Combine everything:

Fold in cooked macaroni, kimchi, kimchi juice, spring onions, and gochujang until well coated

Transfer to baking dish:

Pour the mixture into your prepared dish and spread evenly

Prepare the topping:

Mix panko with melted butter and sesame seeds, then sprinkle over the top

Bake until golden:

Cook for 15 minutes until bubbling and beautifully bronzed on top

Let it rest:

Wait five minutes before serving so the sauce sets slightly and makes serving easier

My roommate walked in while this was baking and literally stood in the kitchen waiting for the timer to go off. The smell of kimchi caramelizing with cheese is something I cannot describe but everyone understands immediately.

Choosing the Right Kimchi

I have learned that older, more fermented kimchi works best because the flavor is deeper and less harsh. Young fresh kimchi can taste too raw and sharp while aged kimchi has that perfect sour-sweet balance that makes this dish sing.

Making It Extra Crispy

For the last two minutes of baking, I switch to broiler mode and watch carefully until the top turns deep golden brown. Just do not walk away because it goes from perfect to burnt in seconds under the broiler.

Serving Suggestions

This dish is rich enough to stand alone but a simple green salad with vinaigrette cuts through the creaminess beautifully. I also love serving it alongside roasted vegetables or as part of a spread with other Korean-inspired dishes.

• A cold beer or crisp Riesling balances the heat perfectly
• Top with extra sliced spring onions for fresh color and bite
• Leftovers reheat surprisingly well in the microwave with a splash of milk

Hope this brings as much joy to your table as it has to mine over the years.

Recipe FAQ

→ Can I make this ahead of time?

Yes, assemble the dish up to 24 hours in advance and refrigerate. Add the topping just before baking. You may need to add 5-10 minutes to the baking time if baking from cold.

→ What type of kimchi works best?

Mature, well-fermented kimchi provides the best flavor. Napa cabbage kimchi is traditional, but any variety works. Drain it well to prevent the sauce from becoming too watery.

→ Can I freeze this?

Freeze the assembled dish (without topping) for up to 3 months. Thaw overnight in the refrigerator, add fresh topping, and bake as directed. The texture may be slightly softer than fresh.

→ How can I make it spicier?

Add extra gochujang to the cheese sauce, incorporate sliced fresh chilies, or use a spicy kimchi variety. A pinch of cayenne pepper in the cheese sauce also works well.

→ What other cheeses can I use?

Sharp cheddar is essential for flavor, but you can replace mozzarella with gruyère, fontina, or pepper jack for different flavor profiles. Keep the ratio similar for proper melting.
