“Turned my holiday ham into something the whole family fought over — five-star comfort from last night’s leftovers.” — home cook review
Reasons to make it:
- Fast: about 20 minutes from pot to plate.
- Budget-smart: stretches leftover ham into new meals.
- Crowd-pleasing: creamy texture and familiar flavors kids and adults accept.
- Flexible: works with diced ham, pancetta, or smoked turkey.
How this recipe comes together
Think of the process as three simple phases:
- Cook the spaghetti until al dente and drain.
- Warm the ham briefly in olive oil to release savory fat and color.
- Combine eggs, cream, and Parmesan, then gently toss with hot pasta off the flame so the sauce thickens into a glossy coating without turning into scrambled eggs.
Key technique: low heat and swift stirring matter. You’re using residual heat to gently coagulate the egg-cream mixture; that’s what gives classic carbonara its velvety texture.
What you’ll need
- 8 ounces spaghetti
- 1 tablespoon olive oil (or butter for richer flavor)
- 1 cup diced leftover ham (about 6–8 ounces)
- 2 large eggs (use pasteurized if serving to pregnant people or infants)
- 1 cup heavy cream (for richness; substitute whole milk + 2 tbsp flour for lighter option)
- 1 cup grated Parmesan cheese (freshly grated for best melt and flavor)
- Salt and freshly cracked black pepper to taste
- Chopped parsley for garnish
Ingredient notes:
- Parmesan: Pecorino Romano can be used for a sharper bite.
- Ham: Thick-cut or smoked ham both work; reduce added salt if your ham is very salty.
- Eggs: If safety is a concern, use pasteurized eggs or briefly cook the sauce to 160°F while stirring.
Step-by-step instructions
- Bring a large pot of salted water to a boil. Cook the spaghetti according to package instructions until al dente. Reserve 1/2 cup of the pasta cooking water, then drain the pasta and set aside.
- While the pasta cooks, whisk together 2 eggs, 1 cup heavy cream, and 1 cup grated Parmesan in a medium bowl until smooth. Season lightly with pepper (cheese and ham add salt).
- Heat 1 tablespoon olive oil in a large skillet over medium heat. Add 1 cup diced ham and sauté just until warmed and slightly caramelized, about 2–3 minutes.
- Reduce the skillet heat to low. Add the drained spaghetti to the pan with the ham and toss to coat. Remove the skillet from direct heat.
- Immediately pour the egg-cream-Parmesan mixture over the pasta and stir quickly and continuously. The residual heat will thicken the sauce; if it seems too thick or clumping, add a splash of reserved pasta water (1–2 tablespoons at a time) until the sauce is glossy and coats the noodles. Aim for a smooth, creamy texture — don’t let the eggs sit on high heat or they’ll scramble.
- Taste and adjust with salt and lots of freshly cracked black pepper. Garnish with chopped parsley and extra grated cheese. Serve at once.
Timing tips: have everything prepped before you drain the pasta — timing is what keeps the sauce silky.
Best ways to enjoy it
Serve in warmed bowls so the sauce stays glossy. Pair with:
- A crisp green salad with lemon vinaigrette to cut richness.
- Steamed or roasted vegetables (broccoli, asparagus, or green beans).
- Crusty bread to mop up sauce.

Wine pairing: a unoaked Chardonnay or a light red like Pinot Noir complements the salty, creamy profile.
Storage and reheating tips
- Refrigeration: Cool leftovers quickly and store in an airtight container up to 3–4 days.
- Freezing: Not recommended; the texture of egg-and-cream sauces degrades when frozen and thawed. If you must freeze, separate pasta from sauce and expect a change in texture.
- Reheating: Warm gently on the stovetop over low heat with a splash of cream, milk, or reserved pasta water to revive creaminess. Microwave in short bursts, stirring between cycles. Do not reheat at high temperatures — that can curdle the sauce.
- Food safety: Because the sauce contains eggs, reheat leftovers thoroughly to at least 165°F for safety. Use pasteurized eggs if serving to immune-compromised people, pregnant women, or infants.
Helpful cooking tips
- Temper the eggs: For extra safety and silkiness, whisk a tablespoon of hot pasta water into the egg-cream mix before adding to the pasta; this raises the temperature gradually and reduces scrambling risk.
- Cheese texture: Freshly grated cheese melts far better than pre-grated.
- Salt sparingly: Taste before salting — the ham and Parmesan can be quite salty.
- pasta water magic: That starchy pasta water is your emulsifier; add it little by little to adjust sauce consistency.
- Timing: Have your egg mixture ready and skillet off the heat before draining the pasta — speed keeps the sauce smooth.
Creative twists
- Swap proteins: Use diced pancetta, bacon, smoked turkey, or leftover roast chicken.
- Lower-fat version: Replace heavy cream with half-and-half or whole milk thickened slightly with a teaspoon of cornstarch.
- Veg-forward: Add sautéed mushrooms, peas, or wilted spinach for color and texture.
- Spicy: Stir in red pepper flakes or a dash of hot sauce for a kick.
- Herbed finish: Fold in basil or chives along with parsley for a fresh lift.
Common questions
Q: Can I skip the cream and still call it carbonara?
A: Traditional Italian carbonara uses eggs and cheese only (no cream). This quick leftover version uses cream to guarantee a velvety sauce with less precise temperature control — it’s a practical, forgiving shortcut.
Q: How do I prevent the eggs from scrambling?
A: Remove the pan from direct heat before adding the egg mixture, stir constantly, and add reserved pasta water gradually. Tempering (whisking a little hot pasta water into the egg mixture first) also helps.
Q: Is it safe to eat eggs that aren’t fully cooked in the sauce?
A: For most healthy adults, properly handled fresh eggs are fine when the sauce is warmed to a safe temperature by the pasta’s residual heat. If serving young children, pregnant people, or immunocompromised individuals, use pasteurized eggs or ensure the mixture reaches 160°F.
Q: Can I double the recipe?
A: Yes — increase cooking vessels as needed. Make sure your pan is large enough to toss the pasta and sauce evenly to avoid uneven cooking.
Q: What’s the best pasta shape for this dish?
A: Long strands like spaghetti, linguine, or bucatini are classic because they carry the silky sauce well, but short tubes will work if that’s what you have.
