This homey dish takes the humble root vegetables carrots and parsnips to elegant, delicious heights by blending them together into a silky puree and serving them with whole wheat pasta in a nutty brown butter sauce.
The carrots and parsnips play particularly well together in this puree as the parsnips are slightly bitter and the carrots have a great sweetness. However, if you can't locate parsnips or just don't like the taste, a puree of straight carrots is equally as compelling and there are a number of other root vegetables that can be subbed in.
The rich, creamy puree is complemented excellently by the simple yet shockingly flavourful herb brown butter sauce, which is compromised of nothing more than browned butter, garlic, fresh herbs, and a shot of lemon for some brightness.
If you desire a little bit of heat, a touch of red pepper flake in the pan with the butter will perfume the entire sauce with a subtle yet gratifying spice.
With a generous serving of root vegetables and whole wheat pasta, this recipe makes for a healthy and satisfying dish that is particularly terrific for cold, rainy nights and reheats splendidly for lunch the next day.
Brown Butters
Brown butter is one the easiest, tastiest, and most versatile sauces to pair with pasta and many other foods. Simply cook the butter for 7-8 minutes until it browns, and it will turn into a magnificent sauce to toss pasta in. As the butter cooks the milk sugars caramelize and develop character and complexity with mature notes of caramelly nuttiness.
In this rendition of brown butter, fresh garlic, thyme, and sage are all toasted in the butter, slowly releasing their flavours and aromas into the sauce.
Depending on your preference or what you have available, all sorts of herbs could be used in brown butter and would pair well with the pasta and puree. Rosemary, basil, chives, and oregano are all herbs that would also be lovely in a brown butter. Although fresh herbs are better, you can also use a small amount of dried herbs with delicious results.
When cooking this brown butter, be sure to cook on low heat and watch it closely, stirring frequently to ensure the butter and garlic don't burn. You're aiming for a dark brown, frothy sauce. If it turns black, you've gone too far.
A good trick when making brown butter for pasta is to reserve a little bit of the pasta cooking water and to add it to the pan with the cooked pasta and butter. The pasta water will add a creamy starchiness to the pan and will help to generously coat the noodles.
Penne in Herb Brown Butter over Carrot-Parsnip Puree

Nutty whole wheat pasta paired with flavourful herbs, lemon and a rich, creamy root vegetable puree. Simple enough for everyday but fancy enough for guests, this dish will level up your pasta game.
Ingredients
Carrot-Parsnip Puree
- 4 carrots (peeled and cut into chunks)
- 4 parsnips (peeled and cut into chunks)
- 1/2 cup heavy cream
- salt to taste
Pasta
- 16 oz whole wheat penne pasta
- 6 tbsp butter
- 4 cloves garlic (minced)
- 2 tbsp fresh sage (cut into strips)
- 8 sprigs fresh thyme
- 1 tsp red pepper flakes (optional)
- 1 lemon (zest and juice)
- 2 tbsp parsley (finely chopped)
- salt and pepper to taste
- 2 tbsp grated parmesan cheese
Directions
Puree
- Place the chopped carrots and parsnips into a pot and cover with cold water. Season liberally with salt.
- Bring the pot to a boil and cook the vegetables for 10-15 minutes or until soft. A good way to tell if they're ready is by piercing a chunk with a small knife. If the vegetable falls right off the knife and starts to fall apart, it's ready.
- Remove the vegetables from the water and place into a blender with the heavy cream. Blend for 1-2 minutes or until it reaches a smooth, pliable consistency. If needed, add a little of the cooking water to thin it out. Season to taste with salt and transfer into pot. Leave on the stove off the heat and set aside.
Pasta
- Bring a large pot of salted water to a boil. Add the pasta and cook to al dente according to the instructions on the package.
- In a large saut pan, heat the butter, garlic, thyme, and chili flakes over low heat. Cook for 7-8 minutes, stirring constantly, ensuring the butter does not burn. It should be bubbly, frothy, and dark brown. Remove the sprigs of thyme from the pan.
- Prepare to strain the pasta. Before straining, reserve 1 ladle worth of the pasta cooking water. Strain the pasta and pour directly from the colander into the pan with the brown butter. Meanwhile, reheat the carrot and parsnip puree.
- Add the lemon zest and juice, the reserved pasta cooking water, and the chopped parsley to the pan. Stir the pasta to combine and cook for 1 more minute. Season to taste with salt and pepper and remove from the heat.
- Use a spoon to spread some of the hot puree around the bottom and sides of the bowl, using about two tablespoons of puree in each bowl. (see photo). Portion pasta in the bowls on top of the puree. Sprinkle some of the grated parmesan on top of the pasta and serve immediately.
