• 2 tablespoons all-purpose flour

Optional Substitutions

• Milk: Use 2% or plant-based milk (unsweetened almond or oat).
• Kimchi: Use mild kimchi for less spice, or add gochujang for extra kick.

• Toppings: Skip breadcrumbs for a keto-friendly version, or add crushed pork rinds.

Instructions

1. Preheat your oven to 400°F (200°C). Scrub the sweet potatoes, prick them with a fork, and rub with olive oil, salt, and pepper. Place on a baking sheet and bake for 35–40 minutes, or until tender when pierced with a fork. Let cool slightly.
2. While the potatoes bake, cook the elbow macaroni according to package directions in salted boiling water until al dente. Drain and set aside.
3. In a large saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1 minute until bubbly.
4. Gradually whisk in the milk and kimchi juice. Continue whisking until the mixture thickens, about 2–3 minutes.
5. Reduce heat to low and stir in the cheddar and mozzarella until melted and smooth. Season with salt and pepper to taste.
6. Fold in the cooked macaroni and chopped kimchi until well combined. If the mixture seems thick, add a splash of milk.
7. Once the sweet potatoes are cool enough to handle, slice each in half lengthwise. Use a spoon to gently mash the flesh inside, creating a well for the filling.
8. Divide the kimchi mac and cheese among the sweet potato halves, mounding it on top. Sprinkle with panko breadcrumbs if using.
9. Return to the oven and bake for 10–12 minutes, until the filling is hot and the breadcrumbs are golden.
10. Garnish with sliced green onions and serve warm.

Pro Tips

• Choose even-sized sweet potatoes so they bake at the same time.
• Don’t overbake the sweet potatoes – they should be tender but still hold their shape.
• Drain the kimchi well to prevent the filling from becoming too watery.
• For extra crispy topping, broil the stuffed potatoes for 1–2 minutes after baking.
• Make the sauce ahead: Prepare the kimchi cheese sauce and refrigerate; reheat gently before mixing with pasta.
• Double the recipe for a crowd – bake on a large sheet pan.
• Use leftover kimchi mac – it’s great on its own!
• Scale the spice: For kids, rinse the kimchi to reduce spice, or start with a small amount.

Variations and Substitutions

• Bacon Kimchi Mac: Add 4 slices cooked crumbled bacon to the mac mixture.
• Vegan Version: Use vegan butter, plant milk, vegan cheese shreds, and omit dairy.
• Spicy Korean Twist: Add 1 teaspoon gochujang (Korean chili paste) to the cheese sauce.
• Loaded Sweet Potato: Top with sour cream, extra cheese, and jalapeños.
• Make it a Meal: Serve with a side salad or steamed greens.
• Cheese Swap: Try half cheddar, half Monterey Jack for a milder flavor.
• Keto Option: Use cauliflower florets instead of macaroni and heavy cream instead of milk.

Storage and Reheating

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 days. The sweet potatoes may soften slightly but still taste great.

Freezer

Assemble the stuffed sweet potatoes without the breadcrumb topping, wrap individually in foil, and freeze for up to 2 months. Thaw overnight in the fridge before baking.

Reheating

Reheat in a 350°F oven for 10–15 minutes, or microwave on high for 1–2 minutes. For crispy topping, use the oven or an air fryer at 350°F for 5 minutes.

FAQ

Can I use leftover mac and cheese? Yes! This is a great way to repurpose leftover mac and cheese – just mix in chopped kimchi and stuff into sweet potatoes.

What if I don't like kimchi? You can reduce the amount or substitute with sauerkraut for a different tang, or omit entirely for classic mac stuffed sweet potatoes.

Can I make this dairy-free? Absolutely. Use vegan butter, unsweetened plant milk, and dairy-free cheese shreds. The sauce may be slightly less creamy but still delicious.

How do I adjust the spice level? Use mild kimchi or drain and rinse it to remove some spice. You can also add less kimchi and supplement with more cheese.

Can I bake the sweet potatoes in the microwave? Yes, for speed. Microwave whole pierced sweet potatoes on high for 5–7 minutes until tender, then proceed with stuffing and baking for 10 minutes.

What other fillings can I use? Try BBQ pulled pork, chili, or buffalo chicken – all work great stuffed into sweet potatoes.

Do I have to use elbow macaroni? No, any small pasta works. Shells, rotini, or penne are good choices.

Can I prepare this ahead of time? Yes. Fully assemble and refrigerate unbaked for up to 24 hours. Bake straight from the fridge, adding 5–10 minutes to the final bake.
