Creamy Spaghetti with Mushrooms, Truffles and Bacon

Quick Answer

This 32-minute creamy spaghetti combines browned mushrooms, smoked streaky bacon, Parmesan and 50 g Minced Black Truffle in Olive Oil for a silky sauce with clear truffle texture. The creamy truffle mushroom spaghetti recipe serves three. Keep the heat low while adding Parmesan, then fold in the minced truffle after the strongest heat has passed so the sauce stays smooth and the truffle aroma and pieces remain noticeable.

Recipe at a Glance

Why This Recipe Works

The sauce is built in layers. Bacon is browned and removed so it stays distinct. Mushrooms cook in the flavour left in the pan, with enough space to release moisture and colour. Cream forms the base, Parmesan thickens it gently and starchy pasta water adjusts the coating.

The truffle ingredient is treated as a finish, not a frying fat. Summer truffle has its own aroma-active profile, and postharvest processing can change its volatile composition (Culleré et al., 2010; Paunović et al., 2023). Reducing the heat before adding the minced product helps retain its recognisable aroma and visible texture. The 2-minute rest lets the pasta and sauce settle before the final consistency check.

For the 32-minute schedule, bring the pasta water to a boil during preparation and cook the bacon while the spaghetti cooks.

Ingredients

For 3 main-course servings:

• 300 g (10.6 oz) dry spaghetti
• 150 g (5.3 oz) smoked streaky bacon, diced
• 15 g (1 tablespoon) unsalted butter
• 300 g (10.6 oz) cremini or button mushrooms, cleaned and sliced
• 1 small onion, about 100 g (3.5 oz), finely chopped
• 2 garlic cloves, finely minced
• 200 ml (about 3/4 cup plus 1 tablespoon) heavy or double cream
• 75 g (2.6 oz) Parmesan, finely grated
• 50 g (1.8 oz) Minced Black Truffle in Olive Oil, divided
• Up to 180 ml (3/4 cup) reserved hot pasta water
• 1/2 teaspoon freshly ground black pepper
• Fine salt, for the pasta water and final seasoning, as needed
• 10 g (about 2 tablespoons) flat-leaf parsley, finely chopped, optional

Ingredient Notes

Minced Black Truffle in Olive Oil is the featured prepared ingredient. Its declared formulation is 70% summer truffle (Tuber aestivum), olive oil, salt and aroma. Use the packing oil and taste before salting. It is not truffle oil; the guide to using truffle oil explains that format.

For successful minced black truffle pasta, stir most of the product into the sauce away from strong heat and fold in the remainder just before the rest. This distributes flavour while keeping some truffle pieces visible. For more about the species named on this product, see the Summer Truffle Guide. The truffle types comparison is useful when comparing prepared products with different declared species.

Choose firm, dry mushrooms and slice them evenly. Finely grated Parmesan melts more readily than coarse shreds. Because bacon, cheese and the truffle product contribute salt, season at the end.

Equipment

• Large pot for spaghetti
• Colander or pasta tongs
• Large, wide frying pan or sauté pan
• Wooden spoon or heatproof spatula
• Fine grater for Parmesan
• Measuring jug or cup for pasta water
• Clean plate for the cooked bacon

Complete Step-by-Step Method

1. Prepare the ingredients. Slice the mushrooms, chop the onion and parsley, mince the garlic, grate the Parmesan and divide the truffle product into 40 g and 10 g portions. Bring a large pot of water to the boil while you work. Keep uncooked bacon and its utensils away from the ready-to-eat ingredients; wash your hands and clean any contacted surface before continuing.
2. Cook the spaghetti. Salt the boiling water moderately and add the spaghetti. Cook according to the package until appropriately firm, usually 8–11 minutes. Before draining, reserve up to 180 ml (3/4 cup) of hot pasta water. Drain without rinsing so the surface starch remains available to the sauce.
3. Brown the bacon. While the pasta cooks, place the diced smoked streaky bacon in the wide pan over medium heat. Cook according to its package directions, stirring regularly, until properly browned and fully cooked, about 6–8 minutes depending on thickness. Transfer it to a clean plate. Leave about 1 tablespoon of rendered fat in the pan and discard any excess appropriately.
4. Brown the mushrooms. Increase the heat to medium-high and add the butter. Add the mushrooms in a broad layer; if the pan is small, cook them in two batches. Leave them undisturbed for 2 minutes, then stir and cook for another 3–4 minutes until their released moisture has mostly evaporated and the edges are browned.
5. Soften the aromatics. Reduce to medium heat. Add the onion and cook for about 2 minutes until softened but not dark. Add the garlic and half the black pepper, then stir for 30 seconds, just until fragrant. Avoid scorching the garlic.
6. Build the cream sauce. Pour in the cream and scrape up the browned flavour from the pan. Let it reach a gentle simmer for 1–2 minutes. Reduce the heat to low or briefly move the pan off the burner. Add the Parmesan in three small additions, stirring each one smooth before adding the next; do not let the sauce boil hard.
7. Coat the spaghetti. Add the drained spaghetti and toss thoroughly. Add reserved hot pasta water 2 tablespoons at a time until the sauce is glossy and moves easily around the strands. It should look slightly looser than the final desired consistency because it will thicken as it rests.
8. Finish with truffle and bacon. Take the pan off strong heat. Fold in 40 g of the Minced Black Truffle in Olive Oil and return all the cooked bacon. Warm gently for no more than 30 seconds if needed, without boiling. Fold in the remaining 10 g truffle product, cover loosely and rest off the heat for exactly 2 minutes.
9. Adjust and serve. Toss once more. If the sauce has tightened, add another spoonful of hot pasta water. Taste before adding fine salt, then add the remaining black pepper. Divide immediately among three warm bowls and finish with the optional parsley.

Food Safety and Allergens

Bacon safety: Smoked streaky bacon products vary. Treat the bacon as requiring cooking unless its label clearly says it is ready to eat, follow the package instructions and cook it completely rather than partially browning it for later. Use a clean plate for cooked bacon and do not reuse utensils that touched the uncooked product until they have been washed (USDA FSIS, 2024; FDA, 2024).

Cooling and reheating: Refrigerate cream, Parmesan and the opened truffle product as their labels direct. Do not leave the finished pasta at room temperature for more than 2 hours. Cool leftovers promptly in shallow containers, keep the refrigerator at or below 4°C (40°F), use refrigerated leftovers within 3–4 days and reheat them to 74°C (165°F) (FDA, 2024a; FDA, 2024b).

Allergens: Cream and Parmesan contain milk. Standard spaghetti contains wheat or gluten, and some pasta also contains egg. Bacon and prepared truffle products may contain additional declared ingredients, so check every package label. This recipe is not presented as allergy-safe (FDA, 2025).

Troubleshooting

Substitutions and Variations

Oyster mushrooms can replace part of the cremini or button mushrooms when cut evenly and browned in batches. Linguine works with the same sauce; short ridged pasta may need more reserved water.

For a bacon-free variation, omit the bacon and add 150 g more mushrooms. Start the pan with the full 15 g butter and season only after the Parmesan and truffle product are incorporated. If vegetarian suitability matters, verify the cheese and all packaged ingredients rather than relying on the dish name.

Do not substitute truffle oil measure for measure: it has a different composition, texture and intensity. For a fresh-truffle variation, keep the sauce and add verified fresh truffle after plating; the Black Truffle Guide explains why species matters.

Serving and Leftovers

Serve the creamy truffle pasta with bacon immediately in warm bowls. A crisp green salad is enough alongside it. For another format, compare the truffle butter chicken pasta recipe or creamy beef and black truffle bowtie pasta.

Store leftovers in a shallow covered container within 2 hours and refrigerate for no more than 3–4 days. Reheat only the portion you need in a pan over low heat, adding a small splash of water or cream and stirring until it reaches 74°C (165°F) throughout. The sauce may be less glossy after chilling, but gradual heat and added moisture help restore the coating. Freezing is possible, but the cream sauce and mushrooms can become grainier or softer after thawing.

Frequently Asked Questions

Can I use another mushroom variety?

Yes. Oyster mushrooms can replace part of the cremini or button mushrooms, provided they are cut evenly and browned without crowding the pan.

Can I omit the bacon?

Yes. Omit the bacon, add 150 g more mushrooms and begin with the full amount of butter; check the Parmesan and packaged ingredients if vegetarian suitability matters.

Can I use another pasta shape?

Linguine is a straightforward substitute. Short ridged pasta also works, but may need a little more reserved pasta water for an even coating.

Why use minced truffle instead of truffle oil?

The minced product contributes visible truffle pieces, olive oil, salt and its declared aroma, so it gives a different texture and seasoning profile from truffle oil.

When should the minced truffle be added?

Add it after the Parmesan sauce and pasta are combined, away from strong heat. Fold in the final portion immediately before the 2-minute rest.

How can I prevent Parmesan from clumping?

Finely grate it, lower or remove the pan from the heat and stir it in gradually. Avoid hard boiling once the cheese is added.

Can I prepare the recipe in advance?

You can prepare the ingredients and brown the bacon shortly before cooking, but combine the sauce and spaghetti near serving time for the best texture.

How should leftovers be stored?

Place them in a shallow covered container within 2 hours, refrigerate at or below 4°C (40°F) and use within 3–4 days.

How should the pasta be reheated?

Reheat one portion gently with a splash of water or cream, stirring until it reaches 74°C (165°F) throughout.

Can I add fresh truffle?

Yes, as an optional finish rather than a replacement for the governed minced product. Add a correctly identified fresh truffle only after plating and keep the species naming precise.
