This dish is easy to divide into make-ahead steps. Roast squash and prepare white sauce the night before, then layer lasagna up to six hours before the party. Just before guests arrive, top with cream and the last layering of Parmesan cheese, then bake.
3/4 cup (3 ounces) grated fresh Parmigiano-Reggiano, divided
1/2 cup whipping cream
How to Make It
Preheat oven to 450°.
Arrange butternut squash in a single layer in a large roasting pan coated with cooking spray. Coat squash with cooking spray. Bake at 450° for 25 minutes or until squash is just tender, stirring once. Set aside.
Lower oven temperature to 350°.
Combine 3 1/2 cups milk and rosemary in a 1-quart glass measuring cup, and microwave at high 5 minutes or until mixture begins to boil. Let stand 10 minutes. Strain milk through a fine sieve into a bowl; discard rosemary.
Lightly spoon all-purpose flour into a dry measuring cup; level with a knife. Combine flour and remaining 1/2 cup milk, stirring flour mixture with a whisk until well blended to form a slurry.
Melt butter in a large saucepan over medium heat. Add garlic; cook 1 minute or until tender, stirring constantly. Stir in steeped milk, and increase heat to medium-high. Gradually add slurry to pan, stirring constantly with a whisk. Cook 15 minutes or until thick, stirring frequently. Remove from heat; stir in 3/4 teaspoon salt and pepper. Combine milk mixture and squash, tossing gently.
Spread about 1 1/2 cups squash mixture into the bottom of an 11 x 7-inch baking dish coated with cooking spray. Arrange 3 noodles over squash mixture; top with 2 cups squash mixture and 1/4 cup cheese. Repeat layers once with 3 noodles, 2 cups of squash, and 1/4 cup of cheese. Top with 3 noodles.
Beat whipping cream and remaining 3/4 teaspoon salt with mixer at high speed until soft peaks form. Spread the whipping cream mixture over noodles; sprinkle with remaining 1/4 cup cheese. Cover with foil coated with cooking spray. Bake at 350° for 30 minutes. Uncover and bake an additional 15 minutes or until golden. Let stand 10 minutes.
I agree with most reviewers that this is very good, but it turned out very soupy for us. I followed the recipe exactly and let it sit for 10 minutes before cutting it, but the sauce was so runny that it was difficult to serve and it made a mess on my plate. Next time I may use less milk or let it sit for longer - or even overnight - before heating individual servings.
Not a bad recipe, but it needs some changes. I didn't like the chunks of squash sitting in the midst of the noodles. I would puree the squash and add it to the milk slurry. Also, I ended up adding a bit more flour because the slurry didn't seem to thicken enough. I added some milk around the lasagna so that the noodles would absorb more liquid and be less dry.
That said, the flavors were good and it's a great way to get rid of all that post-Thanksgiving squash.
Wow this was delicious and easy to make as well. I had it for Chirstmas dinner and it was definitely fit for a special occasion. The only difference I made to the recipe is with the whipping cream because I did not want to use such a high fat ingredient. I took 2% condensed milk and thickened that for the topping which worked very nicely. The lasgana held together well even with the chunks of squash. I have a lot leftover and I am hoping the leftovers will be just as good as the first time!
This recipe was a surprise. It was sweeter than I had expected, but my family enjoyed it. My husband really liked it, but of course said it would be good with some sausage. I skipped the cream on the top and topped with rest of sauce and little parm. cheese.
