Kimchi Mac and Cheese

The first time I combined kimchi with mac and cheese, my roommate looked at me like I had lost my mind. We were both snowed in, cravings were hitting hard, and the only things in our fridge were ajar of kimchi my mom had sent and the basic makings for comfort food. One risky decision later, and I have never looked at regular mac and cheese the same way again.

Last winter, I made this for a dinner party when my friend Sarah announced she was moving to Seoul. She took one bite and immediately asked for the recipe, saying it tasted like home and comfort colliding in the best possible way. Now every time she visits from Korea, this is the first thing she requests.

Ingredients

• 300 g elbow macaroni: The curves catch the sauce perfectly, but any short pasta works in a pinch
• 2 tbsp unsalted butter: Start with this for the roux, plus another tablespoon for that golden topping
• 2 tbsp all-purpose flour: This creates the foundation for your silky cheese sauce
• 500 ml whole milk: Full fat makes all the difference here, trust me
• 150 g sharp cheddar cheese: Go for the aged stuff, it brings that proper cheese punch
• 50 g mozzarella cheese: The secret to that ridiculous cheese pull in every bite
• 1 tsp Dijon mustard: Just a whisper, it makes the cheese taste cheesier somehow
• ¼ tsp ground black pepper: Freshly cracked gives you those little bursts of heat
• ½ tsp salt: Adjust based on how salty your kimchi is
• 200 g kimchi, chopped and well-drained: Squeeze out the extra liquid or your sauce will be too thin
• 1 tbsp kimchi juice: This liquid gold is where all the fermented flavor lives
• 2 spring onions, finely sliced: The bright green pop makes everything look better
• 1 tbsp gochujang: Optional, but honestly, why would you skip it
• 30 g panko breadcrumbs: They get crunchier than regular breadcrumbs ever could
• 1 tbsp sesame seeds: For that nutty finish that makes people ask what your secret is

Instructions

Get your oven ready:

Preheat to 200°C (400°F) and give a medium baking dish a quick grease with butter

Cook your pasta:

Boil the macaroni until just al dente, it will cook more in the oven so do not overdo it now

Start your cheese base:

Melt 2 tablespoons butter over medium heat, whisk in the flour, and let it cook for a full minute

Build that sauce:

Pour in the milk gradually while whisking like your life depends on it, keep going until thickened

Add the magic:

Stir in both cheeses, mustard, pepper, and salt until everything melts into pure velvet

Bring it all together:

Fold in the pasta, kimchi, kimchi juice, spring onions, and gochujang until every piece is coated

Transfer to your dish:

Pour everything into your prepared baking dish and spread it evenly

Make the topping:

Mix panko with the remaining melted butter and sesame seeds, scatter it over the top

Bake until golden:

Let it go for 15 minutes until bubbling and gorgeous, then resist the urge to dive in immediately

Practice patience:

Let it rest for 5 minutes so the sauce sets up slightly, making serving way less messy

My sister insists this is the only mac and cheese her kids will eat now, and she has been making it for every potluck since I shared the recipe with her last year. Something about that combination of familiar comfort and adventurous flavors just works on everyone.

Making It Your Own

I have started adding crispy bacon on top sometimes, and let me tell you, the smoky saltiness takes this to another level entirely. A friend of mine swaps half the cheddar for pepper jack when she wants extra fire.

The Make-Ahead Secret

You can assemble everything up to a day before and keep it covered in the fridge, just add a few extra minutes to the baking time. This saved me when I was hosting dinner and running around like crazy.

Serving Suggestions

A crisp green salad with that sharp vinaigrette cuts right through the richness. Some roasted broccoli or garlicky greens on the side make you feel slightly less guilty about all that cheese.

• Cold beer is basically non-negotiable here
• A dry Riesling complements the heat beautifully
• Leftovers reheat surprisingly well in the microwave

This recipe started as a what-if moment and became the dish I make whenever I need to feed people something that feels like a hug and an adventure all at once. Hope it finds a permanent spot in your rotation too.

Recipe FAQ

→ What does kimchi add to mac and cheese?

Kimchi brings spicy, tangy, and umami-rich flavors that cut through the creamy cheese sauce. The fermentation adds depth and complexity, while the texture provides contrast to the soft pasta.

→ Can I make this dish vegan?

Yes, substitute plant-based butter, milk, and cheese alternatives. Ensure your kimchi is vegan-friendly by checking labels for fish sauce or seafood ingredients. Many brands offer completely vegan versions.

→ How spicy is this kimchi mac and cheese?

The spice level depends on your kimchi choice. Traditional kimchi offers moderate heat, while adding gochujang increases the kick. You can adjust by using milder kimchi or reducing the amount added.

→ Should I drain the kimchi before adding?

Chop and drain the kimchi well to prevent excess liquid, but reserve 1 tablespoon of the kimchi juice. This juice enhances flavor and helps create a velvety sauce consistency.

→ Can I prepare this ahead of time?

Assemble the dish up to 24 hours in advance, refrigerate covered, then bake when ready. Add an extra 5-10 minutes to baking time if baking from cold. The topping is best added just before baking.

→ What cheese works best for kimchi mac and cheese?

Sharp cheddar provides bold flavor that stands up to kimchi's intensity, while mozzarella creates the perfect stretchy texture. Mature cheddar offers even stronger taste for those who love bold flavors.
