Full Ingredients

Frittata Base

• 8 oz (225 g) cooked spaghetti, preferably day-old and lightly sauced or plain
• 6 large eggs
• 3/4 cup (60 g) finely grated Parmigiano-Reggiano, plus more for serving
• 2 tbsp whole milk or water
• 1/2 tsp fine sea salt
• 3/4 tsp freshly ground black pepper
• 2 tbsp extra-virgin olive oil (for frying)

Option A: Pancetta Version

• 3 oz (85 g) pancetta, diced small
• 1 small garlic clove, minced (optional)

Option B: Vegetable Version

• 1 tbsp extra-virgin olive oil (for sautéing veg)
• 1 cup mixed vegetables, diced small (example: 1/2 cup zucchini + 1/4 cup peas + 1/2 cup baby spinach)
• 1 small shallot (or 2 scallions), finely sliced
• 1 small garlic clove, minced
• Pinch of salt

For Serving

• 2 tbsp finely grated Parmigiano-Reggiano
• 1 tbsp chopped flat-leaf parsley

Step-by-Step Instructions

Step 1: Prep the pan and (optional) broiler

Position an oven rack 6 inches from the broiler element and set broiler to High (500–550°F). Use a well-seasoned 10-inch cast-iron or a good nonstick skillet. Have a large plate (or flat lid) ready if you prefer the flip method instead of broiling.

Step 2: Whisk the egg mixture

In a large mixing bowl, whisk the eggs, Parmigiano, milk or water, salt, and black pepper until well combined and slightly frothy. This aeration helps the interior turn tender and custardy.

Step 3: Toss in the spaghetti and let it soak

Add the cooked spaghetti to the bowl and toss with tongs until every strand is coated. Let it stand for 5 minutes so the pasta absorbs some of the egg mixture. If the spaghetti is clumped from the fridge, gently loosen it first; long strands are traditional, but you can roughly cut them in half for easier slicing.

Step 4: Cook your add-ins

For Pancetta: Place the skillet over medium heat. Add pancetta and cook, stirring, until the fat renders and the bits are crisp, 4–5 minutes. If using, stir in garlic for 30 seconds. Transfer pancetta (and garlic) to the spaghetti bowl; wipe the skillet clean.

For Vegetables: Heat 1 tbsp olive oil in the skillet over medium heat. Sauté shallot 1 minute, add zucchini and peas with a pinch of salt and cook until just tender, 2–3 minutes. Stir in spinach and garlic for 30–60 seconds until wilted and fragrant. Transfer vegetables to the spaghetti bowl; wipe the skillet clean.

Step 5: Cook the first side until deep golden

Return the skillet to medium to medium-low heat and add 2 tbsp olive oil. When shimmering, pour in the spaghetti-egg mixture, spreading it evenly. Use a spatula to press down and compact the frittata so it forms a uniform layer, especially around the edges.

Cook without moving, 7–9 minutes. The edges should be crisp and the underside a deep golden brown; the top will be mostly set but still a little moist. Run a spatula around the sides to ensure nothing sticks.

Step 6: Finish the top (broil or flip)

Broiler Method: Slide the skillet under the broiler and cook 2–3 minutes until the top is set and spotty-golden. Keep a close eye; it goes fast.

Flip Method: Place a large plate over the skillet. Carefully invert the frittata onto the plate, then slide it back into the skillet browned-side up. Cook 3–4 minutes more over medium heat until the second side is set and lightly golden.

Step 7: Rest, garnish, and slice

Transfer the frittata to a cutting board or serving platter and rest 5 minutes. Sprinkle with 2 tbsp Parmigiano and chopped parsley. Slice into 6–8 wedges and serve warm or at room temperature.

Pro Tips

• Let the spaghetti soak in the egg mixture for 5 minutes so strands bind and slice cleanly.
• Medium to medium-low heat prevents scorching while the center gently sets.
• Use a truly nonstick or well-seasoned skillet; it makes flipping effortless and edges ultra-crisp.
• For a thicker frittata, use an 8-inch pan and add 1 extra egg; add 1–2 minutes per side.
• Broiling is the easiest way to set the top without risky flipping—just watch closely.

Variations

• Carbonara-Style: Swap pancetta for guanciale and use half Parmigiano, half Pecorino Romano. Add a pinch of black pepper on top.
• Vegetarian Garden: Use a mix of zucchini, peas, spinach, and scallions. Add lemon zest at the end for freshness.
• Mozzarella Core: Scatter 3 oz small mozzarella cubes over the surface before finishing; they’ll melt into gorgeous pockets.

Storage & Make-Ahead

Refrigerate leftovers in an airtight container for up to 3 days. Reheat slices in a lightly oiled skillet over medium heat, 2–3 minutes per side, or in a 350°F oven for 8–10 minutes. An air fryer at 350°F for 4–6 minutes re-crisps the edges nicely. Freezing is possible (wrap slices tightly and freeze up to 1 month), but texture is best fresh; reheat from chilled rather than frozen for the best result.
