From the MyKitchenBank Kitchen

A silky, naturally sweet sauce made from roasted carrots and white beans blended with cream and fresh thyme. The carrots caramelize in the oven, deepening their flavor, while the beans add body and earthiness. Finish with a touch of Parmesan and fresh herbs for a sophisticated pasta sauce that works as well as a soup base.

Steps

Before you start

Preheat your oven to 425°F (220°C)
Have your vegetable broth measured and ready
Drain and rinse canned beans thoroughly, or use freshly cooked beans at room temperature

1
Roast the carrotsOven 425°F / 220°C
- Spread the carrot chunks on a sheet pan and drizzle with 2 tbsp (30 ml) of the olive oil.
- Toss to coat evenly and sprinkle with ½ tsp (2.5 g) of the sea salt and a few grinds of black pepper.
- Roast in a preheated 425°F (220°C) oven for 25–30 minutes, stirring halfway through, until the carrots are tender and the edges are golden brown and slightly caramelized.

Ready when: Carrots are fork-tender with golden, caramelized edges
Tip: Cut carrots to uniform size so they cook evenly; smaller pieces cook faster but may dry out, so keep them to about 1 inch.
2
Sauté garlic
- While the carrots roast, heat the remaining 1 tbsp (15 ml) of olive oil in a large saucepan over medium heat.
- Add the minced garlic and cook, stirring often, for 1–2 minutes until fragrant and just beginning to turn light golden.
- Do not brown.
+ Show details− Hide details
Ready when: Garlic is fragrant and pale golden
Tip: Watch the garlic carefully; it can burn quickly and turn bitter. If it starts to brown deeply, discard and start again.
3
Build the sauce base
- Once the carrots are roasted, add them to the saucepan with the garlic, along with the white beans, vegetable broth, and thyme sprigs.
- Stir well, bring to a simmer over medium-high heat, and cook uncovered for 5 minutes to meld the flavors.

Ready when: Mixture is simmering gently
4
Blend until smooth
- Remove the thyme sprigs and discard.
- Using an immersion blender, puree the sauce until completely smooth, about 1–2 minutes.
- If using a regular blender, work in batches: let the sauce cool for 1 minute, transfer half to the blender (leaving the lid slightly ajar to vent steam), blend on high until silky, and repeat with the second half.
- Pour the blended sauce back into the saucepan if needed.

Ready when: Sauce is completely smooth with no lumps
Tip: When using a regular blender, always leave the lid partially open or remove the center cap to let steam escape; hot liquid can explode if the blender is sealed.
5
Cream and simmer
- Return the blended sauce to medium heat (if it's not already there).
- Stir in the heavy cream and the remaining ¼ tsp (1.5 g) of salt.
- Simmer gently for 3–4 minutes, stirring occasionally, until the sauce is creamy and warm throughout.
- Do not boil, as this can cause the cream to separate.
+ Show details− Hide details
Ready when: Sauce is smooth, creamy, and steaming gently without boiling
Tip: Keep the heat at medium or lower to prevent the cream from breaking or the sauce from separating.
6
Finish and taste
- Remove from heat and stir in the grated Parmesan until fully incorporated and melted.
- Taste and adjust seasoning with more salt, pepper, and the optional lemon juice (which brightens the sweetness of the carrots).
- The sauce should be creamy, velvety, and balanced between sweet carrot flavor and savory umami from the beans and cheese.

Ready when: Parmesan is melted and sauce is well seasoned
Tip: If the sauce seems too thick, thin it with a splash of warm broth or pasta water. If it's too thin, simmer it for another minute or two.
7
Serve
- Ladle the sauce over hot pasta (pappardelle, fettuccine, or penne work beautifully) and toss gently to coat.
- Top with torn fresh basil, a few more shavings of Parmesan, and a drizzle of olive oil if desired.
- Serve immediately.

Tip: Reserve a cup of pasta cooking water before draining; if the sauce becomes too thick when it meets the hot pasta, loosen it with a splash of that starchy water to create a silky coating.

Tips

Roasting the carrots caramelizes their natural sugars, deepening their flavor from merely sweet to complex and almost honeyed. This is the key to making this sauce taste sophisticated rather than cloying.
Blend the sauce smooth for a restaurant-quality texture; lumpy or chunky purees look home-made and lack the silky mouthfeel that makes this sauce special.
Don't skip the Parmesan and lemon juice (if using): together they add savory umami and bright acidity that balance the sweetness of the carrots and richness of the cream, creating a more interesting sauce.
This sauce pairs beautifully with delicate, ribbon-like pasta (pappardelle, fettuccine) or small shapes (penne, fusilli) that catch the creamy sauce. For 4 servings, use about 1 lb (450 g) of pasta.

Make ahead

The sauce can be made up to 2 days ahead. Cool it completely, transfer to an airtight container, and refrigerate. Reheat gently over medium-low heat, stirring often and thinning with a little broth or pasta water if needed. The sauce also freezes well for up to 3 months; thaw in the refrigerator overnight before reheating.

Storage & reheating

Room temperature: up to 1 hour in an airtight container. Refrigerator: up to 4 days in an airtight container; reheat gently over medium-low heat, stirring often. Freezer: up to 3 months in a freezer-safe container; thaw overnight in the refrigerator and reheat gently.

Substitutions

heavy cream → whole milk mixed with 1 tbsp (7 g) cornstarch per ¾ cup (180 ml) milk, or crème fraîche. For a lighter sauce, use whole milk thickened with cornstarch slurry, or swap in crème fraîche for tanginess. The sauce will be less rich but still creamy.
canned white beans (cannellini or great northern), drained and rinsed → chickpeas or butterbeans. Either adds body and earthiness; the flavor will shift slightly but remains delicious. Chickpeas add a nuttier note.
fresh thyme sprigs → 1 tsp (1 g) dried thyme or ¼ tsp (0.5 g) ground thyme, or 2–3 fresh sage leaves. Dried thyme is more concentrated; use half the amount. Sage adds a different herbaceous depth.
vegetable or light chicken broth → light chicken broth or the cooking liquid from canned beans (strained). Chicken broth adds mild savory depth; bean liquid is earthy and thickens the sauce naturally.
