Read our disclosure policy. Brown butter spaghetti served with baby kale and roasted butternut squash. It’s an easy pasta dish to make during busy weeknights! I sure do share lot of pasta recipes. What can I say? I love carbs, especially in the form of noodles. This spaghetti is special because it uses brown butter. Brown butter is my secret ingredient of choice. Not only it is amazing in baked goods like chocolate chip cookies and brown butter peach scones, but the warm, nutty flavor of brown butter does wonders to savory foods. Brown Butter Spaghetti The nutty brown butter works well with the hearty butternut squash, the slight bitterness of the baby kale, and the sweetness from the caramelized onions. Brown butter is created when the milk solids of butter is cooked until fragrant and golden brown. Butter is made up of water, butterfat, and milk solids. As melted butter is headed, the water evaporates and the milk solids separate from the butterfat (thus creating clarified butter or ghee). The milk solids brown in the fat. Those golden specks is what gives brown butter its iconic rich, nutty, warm flavor. Use Fresh Garlic for Pasta Fresh garlic tastes more vibrant and clean compared to jarred minced garlic. Peeling and mincing fresh garlic is well worth the effort. I have a mini mortar and pestle that I absolutely love. For large amounts of garlic, I recommend using this garlic press. Garlic fans will love this spicy garlic shrimp spaghetti or Filipino garlic fried rice. Oven Roasted Butternut Squash Cooking the butternut squash is the most time consuming part of this dish. Cut and prep a whole butternut squash, or save time by purchasing already cut squash. It’s best to roast butternut squash over high heat. Spread the butternut squash chunks over baking sheet. Toss with oil and season well. It will take about 30 minutes to cook. Heat until the squash is soft and can easily be pierced with fork tines. Kale and Other Vegetable Options I highly recommend using baby kale. Although, any variety of kale will work such as dinosaur kale (Tuscan kale) or curly kale. Other great green options include: spinach, baby spinach, or collard greens. If you don’t want leafy greens, you may also used sautéed zucchini, roasted mushrooms, asparagus, or eggplant. Serving Suggestions This brown butter spaghetti sets off an explosion of flavors and smells that causes my belly to do a little dance with every bite. For an even heartier dish, serve this pasta with grilled protein of choice. It’s fantastic with chicken, steak, or shrimp. Although the pasta dish should be served warm, it’s just as tasty at room temperature or chilled. Brown Butter Spaghetti 5 from 1 vote An easy weeknight vegetarian meal. The combination of nutty brown butter paired with sweet butternut squash, earthy baby kale, and umami packed parmesan cheese is unstoppable.

Rosie @ Blueberry Kitchen says: April 21, 2013 Your pasta looks delicious! I’ve never tried brown butter in a savoury dish, I think I need to give it a go! Reply
Allison (Spontaneous Tomato) says: April 24, 2013 This looks so good! And I was just going to make the same comment as the first commenter– I’ve never thought of using brown butter in savory contexts (other than with fish), but brown butter with pasta sounds like the happiest combination! I love baby kale, too… I would have used even more! :) Reply
Danielle says: May 7, 2013 I made this last night and it was delicious! I’m loving your blog, Maryanne!! Reply
Maryanne says: May 7, 2013 Thanks for checking out the blog, Danielle! I’m glad you enjoyed the spaghetti. Its one of my favorites!
Danita says: May 12, 2013 I made this amazing dish last night for 20 plus people. THEY LOVED IT!! THANK YOU VERY MUCH FOR SHARING. Reply
Natalie says: May 21, 2013 Hi, looks delicious! I picked up a bunch of normal kale at the supermarket today (looks a lot frillier than the baby kale in your pic) – would it work in this recipe, or too bitter? Reply
Maryanne says: May 21, 2013 Hi Natalie, normal sized kale should work fine. For large leaves, it would be best to cut off the thick center stalk. Chop or tear large leaves into equal sizes so they cook evenly.
Julia Demmer says: October 5, 2013 Where do you buy the baby kale? I only know the regular size kale… Reply
Maryanne says: October 5, 2013 Hi Julia, I bought my baby kale from Ralphs supermarket. I think the brand was Earthbound Farm Organic. Regular sized kale is totally fine for the recipe.
Julia Demmer says: October 5, 2013 Thank you!! Kale and squash are a great match! I made a salad with (raw) kale and oven roasted butternut squash with a orange/honey/ginger vinaigrette last night…
Julia Demmer says: October 10, 2013 Heu Maryanne! Here’s the vinaigrette recipe: ingredients: 3 tbsp olive oil juice of 1 orange 1/2″ knob of fresh ginger, peeled and minced pinch of salt squeeze of honey To make the dressing, combine the olive oil, fresh ginger, orange juice, salt and honey in a small bowl or mason jar. Stir or shake until well combined – then drizzle dressing over any salad.
Musings from a writer's life says: October 6, 2013 Looks yummy and I’ve put it on my list of dishes to try. I was looking for other ways to eat butternut squash and this looks inspiring! :-) Reply
DH says: October 22, 2013 Made for my cooking club….was so tasty. I used spinach from my garden. :) Reply
Maryanne says: October 22, 2013 Awesome! I bet it taste great with spinach. Oh, how I wish I could grow vegetables :)
Alexis says: October 27, 2013 I used grown up kale, cut up into slices. Left the center stalk in tact and just cooked the Kale a little longer. Added juice from half a lemon. So good! Reply
Maryanne says: October 27, 2013 Kale with a sprinkle of lemon sounds delicious and fresh. Thanks for tip, Alexis!
jrrisk says: October 29, 2013 I made this dish for dinner this evening after finding it on Pinterest. I reduced the amount of onions because I thought two cups was a bit much. Otherwise, it was good. I think next time I might add some pine nuts. Reply
hipfoodiemom says: December 31, 2013 hi there! saw this on Foodie Crush. . omg, love this! going to try this recipe soon! Cheers to you! Reply
Rosalyn Gallo says: November 10, 2020 I was really excited to try this recipe but was disappointed in the end result. Way too much onion and not a distinctive flavor. I would decrease onion to 1/2 cup and add some toasted pecan or walnuts and bacon bit to the finished pasta dish. Reply
Maryanne Cabrera says: November 16, 2020 I’m sorry to hear that. Yes, adding toasted nuts or bacon bits would definitely add another dimension of texture and flavor!
Alex says: December 29, 2022 I’ve tried this dish a few times and I LOVE IT. Everything goes so well together, especially the kale and the squash. I add some ground turkey to make it a full meal. Its one of my favorite meals to take to work!! Reply
