Vegan Sweet Potato and Brussels Sprout Gratin with Marcona Almond-Maple Cream Sauce

OK OK, I know I haven’t shared more Thanksgiving recipes with you. The truth is, I’m a last minute kinda gal. To me, Thanksgiving could be months away – it’s not even on my radar!

But I realize that most normal people have been planning their Thanksgiving recipes for a while now and have probably figured out their menu.

If you haven’t planned yet and you’re last minute like me or there’s wiggle room on your menu – you’re going to want to give this casserole a shot.

Vegan Sweet Potato and Brussels Sprout Gratin with Marcona Almond-Maple Cream Sauce

To be completely honest, I didn’t know how this Marcona almond-maple cream sauce was going to turn out. I thought it might be too blah and not have enough flavor to take the place of a cheesy, milky goodness that’s typical of a casserole of this kind.

Boy, was I wrong. It’s pretty crucial that you use Marcona almonds – they’re a Spanish almond that’s a bit sweeter than the typical almond you buy in the store. I opted for roasted unsalted, but if you can’t find unsalted, slated is fine – just don’t season with salt anywhere else.

The brussels sprouts and raisins offer another savory and sweet touch and a great texture. Of course, we’re using spiralized sweet potatoes here as the layers – their sweetness marries well with the maple in the cream sauce and the raisins.

This casserole is easy to make and can be prepared early in the morning, put in the fridge and then cooked later, closer to the time of Thanksgiving. Let’s talk prep:

And what it looks like after you take it out of the oven:

To shred the brussels sprouts slice the top bottoms off and then slice them into quarters or thirds, lengthwise. Or just take a knife and chop until they look shredded – there’s no specific way they really need to be “shredded,” just as long as they aren’t in thick chunks – you want them leafy.

If you want to avoid using added sodium and loathe broths, you can swap in almond milk for the vegetable broth here – it will create a slightly thicker consistency that’s just as delicious.

I’m sorry for the delay in the Thanksgiving recipes! I’m going to do a roundup tomorrow to make up for it, I promise!

Nutritional Information & Recipe


Vegan Sweet Potato and Brussels Sprout Gratin with Marcona Almond-Maple Cream Sauce

Prep Time20 mins
Cook Time45 mins
Total Time1 hr 5 mins
Servings: 4


  • 1 tablespoon extra virgin olive oil
  • 3 tablespoons diced shallots
  • 3 cups shredded brussels sprouts
  • salt and pepper to taste
  • 1/3 cup raisins
  • 2 medium sweet potatoes peeled
  • For the almond cream sauce:
  • 1 cup roasted unsalted marcona almonds – without skin (if you can’t find these, roasted and unsalted regular almonds will do)
  • 1 cups low-sodium vegetable broth
  • 1 tablespoon maple syrup
  • 2 large garlic cloves peeled and smashed


  • Preheat the oven to 425 degrees. Grease a 10” cast-iron skillet with cooking spray and set aside.
  • In a large skillet, add in the olive oil. Once oil heats, add in the shallots and let cook for 1 minute or until fragrant. Add in the brussels sprouts and season with salt and pepper. Cook for 3 minutes or until almost cooked through, stirring frequently. When done, transfer to a medium bowl, add in the raisins, toss to combine and set aside.
  • While brussels sprouts cook, combine all of the ingredients for the dressing into a high-speed blender (I used my Nutribullet) until creamy, about 2 minutes. Set aside.
  • Slice the sweet potatoes halfway through lengthwise, careful not to pierce farther than the center. Spiralize the potatoes using Blade A.
  • In the bottom of the prepared cast iron skillet, add in a layer of the sweet potatoes. Top with a layer of the almond cream sauce and then top that with a layer of the brussels sprout-raisin mixture. Top that with another layer of the sweet potatoes, then another layer of the almond cream sauce and then top with the rest of the brussels sprout-raisin mixture. Top the brussels with the remaining sweet potatoes and top with the remaining almond cream sauce.
  • Cover the skillet with tinfoil and bake for 40 minutes. Remove the foil and bake for 5-10 more minutes or until sweet potatoes are easily pierced with the fork.
  • Let cool for at least 5 minutes and then serve.

Oh, I am SO making this for Thanksgiving this year! But I think I will substitute dried cranberries for the raisins. Thank you!!! This combines my two favorite fall sides -- brussels sprouts and sweet potatoes.
Dried cranberries would be amazing!

Could you please explain about slicing the sweet potatoes half way through. Thx

BTW, for some reason the photos are not showing up for this post. Is it you or is it me?
I tried on two different browsers and they show up!
Carolyn M. says:
Yes, they showed up a little while later for me. Don't know what the problem was, but it's fine now.

Sounds delicious and i plan to try it for Thanksgiving. Am i just not seeing it or is the nutritional info missing. Do you happen to know the nutritional info so i can figure out weight watcher points plus?
I've added it in! Thanks :)
Meagan La Plante says:
I just made this recipe. For some reason the sauce didn't get creamy at all. I am going to try baking it like that anyway, but it's fairy watery. Any suggestions?
Anonymous says:
Once you make it, the sauce firms up and becomes creamy!
This looks absolutely delicious and I cannot wait to make it! I don't have a cast iron skillet though, can you recommend something similar that would work??
You can try a regular 10" nonstick skillet! Or, a small casserole dish!
Jenn says:
Do you have any suggestions to substitute the almonds (nut allergy)?
You can use boiled cauliflower for a similar consistency!

Can this dish be made ahead? If so, how far in advance?? My fear would be that the veggies get mushy...

Where is the actual instructions for the sauce?

ramen is the perfect meal for this season of life. it’s cozy, comforting, filling, and satisfying. 🙏🏼 needless to say, I’ve been eating tons of ramen bowls lately, and I’m extra excited to share this one with you, a take on Japanese miso ramen: Miso Noodles with Smoky Tempeh (using @lightlifefoods Original Tempeh) and Kale. 🥬 🍜 #LightlifePartner⁣

this is kind of like two recipes in one, because this smoky tempeh is good on everything – in sandwiches, on salads, in grain bowls - it’s my go-to flavor when I’m making tempeh (especially for those who aren’t as far along on the tempeh train as I am.) the other recipe is the simplest miso ramen with kale, which you’ll be making over and over again. 👏🏼 also, you can simply sub in @lightlifefoods’ Smoky Tempeh product here, to save time!⁣

you can find @lightlifefoods Original Tempeh at @acmemarkets or @wholefoodsmarket, but use their Store Locator on their site to find out where it’s sold near you. 🛒⁣

recipe below 👇🏼👇🏼⁣

Miso Ramen with Smoky Tempeh and Kale⁣
Serves: 4⁣

2 tablespoons extra virgin olive oil⁣
8-ounce package @lightlifefoods Original Tempeh, cubed⁣
¼ cup soy sauce, low sodium⁣
2 tablespoons maple syrup⁣
¼ teaspoon smoked paprika⁣
1 teaspoon liquid smoke⁣
1/2 teaspoon garlic powder⁣
2 garlic cloves, minced⁣
1-inch knob ginger, minced⁣
4 cups vegetable broth⁣
1 tablespoon miso paste⁣
1 tablespoon low-sodium soy sauce⁣
4 cups finely chopped kale⁣
12 ounces ramen noodles⁣

Heat half the oil in a large skillet over medium heat. Add the tempeh slices and cook for 5 minutes until browned, stirring frequently.⁣

While tempeh cooks, stir together ¼ cup of water, soy sauce, maple syrup, smoked paprika, liquid smoke, and garlic powder. Pour that over the cooked tempeh and stir to coat. Let cook another 5 minutes or until moisture is evaporated and tempeh is browned. Set aside on a parchment lined plate.⁣

Heat the remaining oil in a large pot over medium-high heat. Once oil is shimmering, add the garlic and ginger and cook for 1 minute or until fragrant. Add the broth and 2 cups of water and bring to a boil over high heat.

taco mondays are the new taco tuesdays! 🌮 but seriously... every day is a good day for a taco, right? 🥑⁣

the whole family loved these tonight, so I figured I'd share the recipe with you all! for so long, I over-thought fish tacos and now, I've got them down to a pretty easy science: slaw in an avocado sauce, a garnish, and pan seared cod. oh, and some quality corn tortillas, warmed in a skillet first (it makes such a difference!) 👇🏼⁣

cod fish tacos⁣
makes 9 tacos (3 servings) ⁣

ingredients ⁣
~ 1 ripe avocado⁣
~ 1 lime, juiced⁣
~ 1 small garlic clove, sliced⁣
~ 1 large handful cilantro⁣
~ salt and pepper⁣
~ 4 cups coleslaw mix ⁣
~ 9 corn tortillas ⁣
~ avocado oil ⁣
~ 3 boneless, skinless cod filets (about 3-ounces each) ⁣
~ 2/3 cup pineapple mango salsa (or similar) ⁣

in a food processor, place the avocado, lime, garlic, cilantro, 1/4 cup water, and season with salt and pepper and process until smooth. place the coleslaw in a large bowl and add the avocado crema and toss to coat. set aside.⁣

warm the tortillas in a large skillet and set aside, 3 on a plate. ⁣

add the oil to the skillet and once oil is hot, add the cod. cook for 5 minutes, flip, and cook another 5 minutes or until the cod flakes and is opaque. using a spatula, break the cod up into pieces. divide the cod onto the warmed tortillas. top with avocado slaw and mango salsa. serve.⁣
