I have a confession. Since January 2026, I have been living every single day as if a camera crew is following me. Not literally, of course—I am a normal home cook—but in my head, every dinner is an episode of an imaginary culinary competition. The other night, the challenge was simple: make something interesting with winter squash in under an hour. What could possibly go wrong?

I threw open the fridge. There it was: a few thick wedges of red- and green-skinned kabocha squash, a little container of diced pancetta left over from my spaghetti carbonara tests, half a wedge of Pecorino Romano, and eggs. My brain whispered the magic question: What else is carbonara? I had no idea I was about to turn pasta sauce ingredients into a roasted squash topping. But that is exactly what happened.

Why do we forget that leftovers are just future recipes waiting for a plot twist? I sliced the squash about 3/4 inch thick, tossed it with olive oil, salt, and pepper, and spread it on two rimmed baking sheets. Then I shoved everything into a 425°F (220°C) oven. The clock started ticking. Would forty-five minutes be enough to get those caramelized edges? Spoiler: yes.

While the squash roasted, I turned to the pork. I crisped the pancetta in a skillet with a little olive oil and a few sprigs of fresh thyme. As the fat rendered, the kitchen filled with that intoxicating aroma—salty, savory, slightly funky. I removed the thyme, then added red wine vinegar, more extra-virgin olive oil, minced parsley, and chives. Does that sound like a vinaigrette? It should, because it is: a warm pork fat and olive oil vinaigrette, which is exactly the kind of phrase that would make imaginary judges applaud.

Also on my stove, two eggs were boiling. I pulled them at exactly eleven minutes, dropped them into an ice bath, and peeled them. Here comes the silly part. I halved the eggs, scooped out the yolks, and crumbled them into a small bowl like golden confetti. The whites? I looked straight ahead—past the imaginary lens—and said, 'Cook's privilege.' Then I ate them. Don't judge me. You would do the same.

Once the squash was tender and browned, I lifted the slices carefully with a thin metal spatula. Kabocha can stick if you rush it, so patience is key. I arranged everything on a platter—some slices still steaming, edges dark and crisp. Then came the fun: spooning that warm vinaigrette all over the top. The vinegar cut through the richness while the olive oil and pork fat coated every ridge. Finally, I scattered the crumbled egg yolks and grated Pecorino Romano and Parmigiano-Reggiano over everything. A few cracks of black pepper, and I stepped back.

Was it pasta? Not at all. Was it carbonara? Not in the classic sense. But did it capture everything I love about carbonara—the pork, the cheese, the pepper, the egg-yolk richness—without a single strand of spaghetti? Absolutely. The roasted squash brought sweetness and earthiness that the pasta never could. Every bite had crispy edges, creamy yolk bits, sharp cheese, and that glossy, slightly acidic pork fat vinaigrette. I may have whispered, 'Chef-Champ,' to no one.

So, if you ever find yourself in a made-up cooking competition with a butternut squash and some leftover carbonara components, remember this: riffs on something old are almost always better than brand-new ideas. The formula is simple.

Here is what I used for 4 to 6 servings:

  • 3 1/2 pounds kabocha squash, trimmed, seeded, sliced 3/4 inch thick

  • 6 tablespoons extra-virgin olive oil, divided

  • Kosher salt and freshly ground black pepper

  • 4 ounces diced pancetta, guanciale, or bacon

  • 4 sprigs fresh thyme (optional)

  • 2 teaspoons red wine vinegar

  • 1 tablespoon each minced flat-leaf parsley and chives

  • Yolks from 2 large hard-boiled eggs, finely crumbled

  • Grated Pecorino Romano and/or Parmigiano-Reggiano, for garnish

And the game plan:

  1. Preheat the oven to 425°F (220°C). Toss squash with 2 tablespoons olive oil, salt, and pepper. Roast on two rimmed baking sheets until browned and tender, about 45 minutes. Let cool slightly.

  2. Meanwhile, cook the pork with 1 tablespoon olive oil and thyme over medium heat until crisp, about 7 minutes. Remove thyme. Stir in vinegar, remaining 3 tablespoons olive oil, parsley, and chives. Keep warm.

  3. Lift the squash with a thin metal spatula, arrange on a platter, and spoon the warm vinaigrette on top.

  4. Garnish with crumbled egg yolks, grated cheese, and more black pepper. Serve immediately.

One last thought: if this recipe does not win over your imaginary audience, you can always blame the squirrels. They never cooperate.
