15-Minute Zucchini Carbonara for Two with Lemon
A vegetarian twist on Roman carbonara that swaps guanciale for fresh zucchini, keeping the silky egg-and-cheese sauce at its heart. Tender pasta ribbons or tubes mingle with delicate diced zucchini in a creamy, lemon-bright coating finished with cracked black pepper and Parmesan. Perfect for a quick weeknight dinner for two, this version delivers carbonara's richness without meat, letting the pasta and subtle citrus shine. The 8-minute cook time makes it ideal when you want restaurant-quality comfort food fast.

Tips
Keep the egg bowl away from heat until tossing with hot pasta; residual heat cooks the eggs into creamy sauce without scrambling. Work quickly after draining.
Reserve pasta water generously before draining. A spoonful of starchy water adjusts sauce consistency better than cream or extra cheese.
Use freshly grated Parmesan and zest the lemon just before cooking; both lose potency quickly and define this dish's bright, sharp flavor.
Good to Know
Leftovers keep 1 day refrigerated in airtight container. Reheat gently in a pan with splash of water over low heat, stirring constantly, to avoid curdling eggs. Do not microwave.
Prep zucchini and grate cheese up to 4 hours ahead. Zest lemon and beat egg mixture just before cooking. Pasta must be made fresh to order.
Serve immediately in warmed shallow bowls. Pair with crisp white wine (Pinot Grigio, Vermentino) or light sparkling wine. Add a simple arugula salad with olive oil and lemon on the side.
Common Mistakes
Do not add cold eggs to hot pasta or they will scramble; toss immediately after draining while pasta is still hot to slowly cook the eggs.
Do not skip reserved pasta water; it contains starch that emulsifies the sauce into silky consistency.
Do not overcook zucchini or it will turn to mush; add it in the last 2 minutes when pasta is nearly done.

FAQ
Can I make this without egg yolks?
Not successfully. Egg yolks are essential to carbonara's creamy texture. A substitute like cashew cream will work but creates a different dish entirely. This recipe requires eggs.
What if I don't have fresh Parmesan?
Use aged Parmesan (Parmigiano-Reggiano is ideal) or Pecorino Romano. Avoid pre-grated; it contains anti-caking agents that prevent smooth sauce. Grate by hand just before use.
How long can I keep carbonara in the fridge?
Up to 1 day in an airtight container. It loses silky texture as eggs firm up. Reheat gently over low heat with a splash of water, stirring constantly. Freezing is not recommended.
