For this bake, the star is the sweet potato, whose caramelized edges provide a subtle sweetness that pairs perfectly with the smoky chili sauce. Pasta offers a comforting base, while a splash of cream adds richness without overwhelming the spice. Fresh herbs and a touch of cheese finish the dish with bright, savory notes.
Main Ingredients
- 2 medium sweet potatoes, peeled and cubed (≈ 1½ lbs)
- 12 oz (340 g) short‑rib pasta or penne
- 1 cup heavy cream or coconut cream (for dairy‑free)
Chili Sauce
- 1 tablespoon olive oil
- 1 small onion, finely diced
- 2 garlic cloves, minced
- 1½ cups canned diced tomatoes
- 2 teaspoons chili powder
- ½ teaspoon smoked paprika
- ½ teaspoon ground cumin
Seasonings & Garnish
- Salt and freshly ground black pepper, to taste
- ¼ cup grated Parmesan or nutritional yeast
- 2 tablespoons fresh cilantro or parsley, chopped
The sweet potatoes bring a mellow caramel note that balances the chili’s smoky heat, while the cream softens the sauce for a velvety texture. Pasta acts as the perfect vehicle for the sauce, ensuring every forkful is coated. Finishing with Parmesan and fresh herbs adds a salty, herbaceous lift that rounds out the flavor profile beautifully.
Step-by-Step Instructions

Roasting the Sweet Potatoes
Preheat the oven to 400°F (200°C). Toss the cubed sweet potatoes with a drizzle of olive oil, a pinch of salt, and a dash of smoked paprika. Spread them on a parchment‑lined baking sheet and roast for 20‑25 minutes, turning once, until they are golden‑brown and tender. Roasting concentrates their natural sugars, adding depth to the final bake.
Preparing the Chili Sauce
- Sauté aromatics. In a large skillet over medium heat, warm 1 Tbsp olive oil. Add the diced onion and cook 4‑5 minutes until translucent. Stir in the minced garlic and cook another 30 seconds, being careful not to let it brown.
- Build the sauce. Add the diced tomatoes, chili powder, cumin, and smoked paprika. Simmer for 8‑10 minutes, allowing the flavors to meld and the sauce to thicken slightly. Scrape any browned bits from the pan—they’re flavor gold.
- Incorporate cream. Reduce the heat to low and stir in the heavy cream. Cook for an additional 2‑3 minutes until the sauce is glossy and coats the back of a spoon. Season with salt and pepper to taste.
Cooking the Pasta
While the sauce simmers, bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente, usually 9‑11 minutes. Drain, reserving ½ cup of the pasta water, and set aside. The starchy water will help bind the sauce to the pasta later.
Assembling the Bake
- Combine ingredients. In a large mixing bowl, gently toss the roasted sweet potatoes, cooked pasta, and chili‑cream sauce. If the mixture seems dry, add a splash of the reserved pasta water.
- Transfer to baking dish. Evenly spread the mixture in a greased 9‑x 13‑inch casserole dish. Sprinkle the grated Parmesan (or nutritional yeast) over the top for a golden crust.
- Bake. Place the dish in the preheated 400°F oven for 15‑18 minutes, until the cheese melts and the edges turn lightly crisp. A visual cue is a bubbling surface with a light brown top.
Finishing Touches
Remove the bake from the oven and let it rest for 5 minutes. This short rest lets the sauce settle and the flavors meld. Sprinkle the chopped cilantro or parsley just before serving for a fresh, aromatic finish. Serve hot and enjoy the comforting blend of sweet, spicy, and creamy notes.
Tips & Tricks
Perfecting the Recipe
Uniform Sweet Potato Cubes: Cut the potatoes into ½‑inch pieces so they roast evenly and develop a consistent caramelization.
Don’t Over‑cook Pasta: Al dente pasta holds its shape during baking, preventing a mushy texture once the sauce thickens.
Use a Heavy‑Bottom Skillet: This distributes heat evenly when sautéing aromatics, reducing the risk of scorching the garlic.
Flavor Enhancements
Stir in a tablespoon of tomato paste with the diced tomatoes for deeper umami. Finish the bake with a squeeze of fresh lime juice for bright acidity, and add a pinch of red‑pepper flakes if you crave extra heat.
Common Mistakes to Avoid
Skipping the resting time after baking causes the sauce to run off the plate. Also, avoid adding too much cream early; it can thin the sauce before the flavors have a chance to concentrate.
Pro Tips
Toast the Spices: Briefly toast chili powder, cumin, and smoked paprika in a dry pan before adding them to the sauce for an amplified aroma.
Season in Layers: Salt the sweet potatoes before roasting, season the sauce while it simmers, and finish with a final pinch of salt after baking for balanced seasoning.
Use a Crumb Topping: Mix breadcrumbs with a little melted butter and sprinkle over the cheese for an extra crunchy top.
Variations
Ingredient Swaps
Replace sweet potatoes with butternut squash for a milder flavor, or use chickpeas for a plant‑based protein boost. Swap the short‑rib pasta for gluten‑free penne or spiralized zucchini to change the texture. For a smoky twist, add a handful of chipotle peppers in adobo sauce.
Dietary Adjustments
To make it vegan, use coconut cream and nutritional yeast instead of dairy. For a low‑carb version, substitute the pasta with shirataki noodles or cauliflower rice. Gluten‑free diners should choose certified gluten‑free pasta and check that any packaged sauces are free from wheat.
Serving Suggestions
Pair the bake with a simple arugula salad dressed in lemon vinaigrette, or serve alongside warm cornbread to soak up the sauce. A side of roasted Brussels sprouts adds a crisp, bitter contrast that balances the dish’s richness.
Storage Info
Leftover Storage
Cool the bake to room temperature, then transfer portions to airtight containers. Refrigerate for up to 4 days. For longer keeping, freeze in a single‑serve container for up to 3 months; wrap tightly with plastic wrap before adding a foil lid to prevent freezer burn.
Reheating Instructions
Reheat in a pre‑heated 350°F oven, covered with foil, for 15‑20 minutes until hot throughout. For a quicker option, microwave a portion on medium power for 2‑3 minutes, stirring halfway, and add a splash of broth or extra cream to restore moisture.
