Ingredients You’ll Need

This recipe relies on high-quality pantry staples and fresh seasonal produce.

1 medium spaghetti squash (approx 3 lbs)
4 oz guanciale or pancetta, diced
3 large whole eggs
2 large egg whites
0.5 cup Pecorino Romano cheese, finely grated
0.5 cup Parmesan cheese, finely grated
1 teaspoon freshly cracked black pepper
0.5 teaspoon kosher salt

Step-by-Step Cooking Steps

Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
Slice the spaghetti squash in half lengthwise and remove the seeds with a spoon.
Place the squash halves cut-side down on the baking sheet and roast for 40 to 45 minutes until the skin is easily pierced with a fork.
While the squash roasts, whisk the whole eggs, egg whites, grated Pecorino Romano, and Parmesan together in a bowl until combined.
Sauté the diced guanciale in a large skillet over medium heat until the fat has rendered and the meat is crispy.
Remove the skillet from the heat source and set aside briefly.
Once the squash is cooked, use a fork to scrape the flesh into long spaghetti-like strands.
Add the squash strands to the skillet with the guanciale and toss to coat in the rendered fat.
Quickly pour the egg and cheese mixture over the warm squash strands, tossing constantly and vigorously to create a creamy emulsion using the residual heat.
Season with salt and extra black pepper, and serve immediately to maintain the sauce texture.

Best Ways to Enjoy It

Serve this dish warm while the sauce is still silky and glossy. It looks stunning when topped with an extra sprinkle of cheese. Add a crack of fresh pepper for that authentic look.

Pair it with a simple arugula salad for a fresh crunch. A glass of crisp white wine makes it feel like a special occasion. It is a fantastic way to impress your dinner guests.

How to Store Leftovers

Store any leftovers in an airtight container in the fridge. They will stay fresh for up to three days. Reheat gently on the stovetop over low heat.

Avoid the microwave to keep the sauce from curdling. You might need a splash of water to loosen it up. This makes for a fantastic high-protein lunch the next day.

Pro Tips

Use room temperature eggs to ensure the smoothest sauce possible.
Do not overcook the squash or it will become mushy.
Grate your own cheese for a much better melt.
Whisk your eggs vigorously to avoid any scrambled bits.
Always save the black pepper for the very end.
Work quickly once you add the egg mixture to the pan.
If the squash is too wet, pat it dry before tossing.

Ways to Switch It Up

Swap guanciale for thick-cut bacon if you cannot find it.
Add a handful of fresh spinach for extra greens.
Stir in some roasted garlic for a deeper flavor profile.
Top with red pepper flakes for a spicy kick.
