Butternut squash melts into the polenta as it cooks for this creamy make-ahead dish. Once transferred to a baking dish, pressing chunks of creamy Fontina cheese into the polenta ensures that once baked it will be full of gooey pockets of cheese throughout.

Ingredients

10–12 servings

1 Tbsp. kosher salt, plus more
1 cup coarse polenta (about 5 oz.)
1 medium butternut squash (about 2 lb.), peeled, seeds removed, cut into 1" pieces
2 cups whole milk
¼ tsp. freshly grated nutmeg
1½ oz. Parmesan, finely grated (about ½ cup)
¼ cup (½ stick) unsalted butter, cut into pieces, plus more for pan
3 Tbsp. extra-virgin olive oil
¾ cup sage leaves
½ lb. Fontina cheese, cut into ½" pieces
  1. Step 1

    Combine 1 Tbsp. salt and 6 cups water in a large pot and bring to a boil. Gradually whisk in polenta, then cook over medium-high heat, whisking constantly, until polenta just begins to thicken, about 5 minutes. Stir in squash, reduce heat to medium-low, and continue to cook, stirring occasionally, until polenta is thick and no longer gritty, and squash mashes easily when pressed with the back of a spoon, 30–40 minutes.

    Step 2

    Mix in milk and nutmeg, increase heat to medium-high, and cook, stirring constantly and smashing squash with the back of spoon, until squash is dissolved into the polenta, 10–15 minutes. Remove from heat and stir in Parmesan and ¼ cup butter until melted. Let cool slightly.

    Step 3

    Meanwhile, heat oil in a large skillet over medium-high until shimmering. Add sage and cook, stirring, just until leaves are lightly crisped and darker in color, about 1 minute. Using a slotted spoon, transfer sage to a paper towel-lined plate to drain.

    Step 4

    Grease a shallow 3-qt. baking dish with butter, then transfer polenta mixture to baking dish. Scatter Fontina cheese over and press down lightly with spoon to submerge. Top with crisped sage. Let cool to room temperature, then cover and chill overnight and up to 2 days.

    Step 5

    Preheat oven to 375°F. Uncover dish and bake casserole until bubbly and lightly browned on top, 30–35 minutes. Let sit 10 minutes before serving.

  • Ok, was looking for a cornmeal and squash dish for Thanksgiving after reading that cooked cornmeal was a staple food of the Wamponoag people- the ones who actually saved the "Pilgrims" from dying in 1620-21. So this was it-- I followed the liquid reduction suggested in comments (3.5 cups veg stock to 1 cup polenta, with only a little splash of milk) and it was great. Yum to those chunks of fontina (not Wamponoag appropriate, but delicious!) Big hit.

  • This is a delicious dish. I made it as written, 2 Thanksgivings ago, and it was loved by all. Made much more than 3 Quarts, however. Had to put the extra in another 2 quart casserole. It was super thick and cheesey. I don't know why some others found this to be soupy. I had to search for Course Cornmeal, but maybe that's why I had the perfect consistency. A great recipe for the Fall and Winter months, and would be quite filling serving as a main course as well.

  • 很明显,这不是脆,公司可能带来的-fried polenta. This is grits style, serve-in-a-bowl polenta. Based on other reviews, I even increased my polenta to liquid ratio. Just know that going in.

  • This was one of the most disappointing recipes I've ever made from Epicurious, and I've made a lot. I made it EXACTLY as the recipe states... no substitutions, no Instapot (wtf!?!?) sage from my garden, and I left it 24 hours in the fridge before baking. What did I get? Cheesy cornmeal soup. My toddler wouldn't even eat it.

  • 我从来没有写过评论配方,直到没有w. That's how strongly I feel about this polenta. This is my new favorite. But...I did make some changes after reading the other reviews (but not many!) so bear with me. First - I made it in the instant pot. Yup. It's so fast, why not!? Reduce water to 3.5 cups, salt to 2 tsp, and add the polenta and squash. High Pressure for 10 min, natural release. Mash contents. SKIP the milk. Add the butter and parmesan. Don't skip the sage - it is sooo good. I will make this again before the week is done. YUM! Perfect consistency and even picky children liked it. Everyone wanted seconds.

  • I'm not sure how that much squash and cheese can be so tasteless, but the texture was like glop, too. A hard 'no' on this one in my family.

  • Wow, this was a big hit at a Christmas dinner. Left out the sage which left room for more gooey brown cheese. Maybe a touch too salty but loved it. Also since many noted it was too runny, I used extra polenta and less water. I made a half recipe but used 3/4c polenta and 4c water.

  • UPDATE to my earlier review. I made chowder from the leftovers. I heated up the leftover casserole, mixed in some turkey broth in about equal parts, and added some frozen corn kernels. It was very good!

  • I love squash and polenta and sage so this was a natural....I loved the taste, but as another reviewer stated it was just a little too runny for me. I roasted the squash ahead and mixed with the partially cooked polenta. I really like sage, so I chopped some and added into the mixture with a pressed garlic clove. The flavor was divine, but consistency (even after cooking double the time) was just this side of soupy. Next time I will use 2 cups of polenta to one squash. That should firm it up some. But, for sure there will be a next time.

  • Very tasty, we all loved the flavors BUT: It took forever to get the squash to be soft enough to mash with the back of a spoon and "melt" into the polenta. I spent almost 2 hours on prep, thankfully started the the night before. I cut and cooked the squash as directed. Next time (if I bother, which is doubtful) I'd cut it even smaller or maybe precook it a bit. The final result was more than gooey, it was downright soupy. Ran all over the place and would have worked better in a bowl. I'm surprised no one else commented on this, making me wonder if I erred somehow, although to my knowledge I followed the recipe pretty exactly and have a reliable oven

  • I´m in the midst of making this for the second time. The first time I adapted it to flavors of Manabí, the province in Ecuador famous for superb gastronomy. My question this time, since I want to use the crisped sage this time: will it really stay crisp if it sits on the casserole for days at a time? Wouldn´t it be better to place it on top right before the final baking?

  • Really tasty. Gooey, cheesy goodness. For my taste, a little on the sweet side - but a few dashes of Tabasco gave it acidity and heat to balance the sweet.

  • Would smoked gouda work instead of Fontina cheese?
