This is a quick and easy preparation that can be used for most any winter squash. Another option is to cook the squash whole, then slice it in half. Add the knob of butter and a sprinkling of sugar to each half and finish it off under the grill.
This is the only way I've ever had squash but you can do it a quicker way. Cut it in half and seed it. Microwave on high for 5 minutes. Put about a tablespoon of butter in each have and spread it around on the top edges and inside. Litely sprinkle nutmeg all over and then about twice as much cinnamon. Follow it up with brown sugar (1-2T each half depending on how sweet you like it) and bake at 350 for about 20 minutes. Feel free to turn the oven off and keep the squash in there until the rest of your meal is done. You just can't miss with squash this way! - 10 Oct 2006 (Review from Allrecipes US | Canada)
This is a great recipe. I love the butter and brown suagr flavor, but I cook mine differently. I use the same amount and same ingredients, but I cut the acorn squash in half, place flesh side up and place into a casserole dish or a roasting pan with a little water. I put the butter and brown sugar in the middle before I cook it. Then I cook in a 350 degree oven for 45-60 mins. Comes out perfect every time. If the squah is a little unstable, I cut the bottom just a little to make it stand up better. I'll do about 2 squash at a time (4 servings). - 30 Nov 2005 (Review from Allrecipes US | Canada)
You can make this same recipe in the microwave. Just place squash halves cut side down in a microwave tray with 1/2 cup water per two halves. Cook 10-15 min until tender. Then turn over and fill with butter and sugar. Cook until butter melts. - 07 May 2001 (Review from Allrecipes US | Canada)
