Alternatives to roasting squash for soup? Premise that you can access merely an electric range, and can't access any functioning oven, not even a toaster one. Then what can you do in lieu of roasting your squash? Pan-fry or caramelize it in a cast-iron skillet?

Roasted Acorn Squash and Apple Soup - Making Thyme for Health


  I find that acorn squash is a little bit harder to peel and chop so I decided to roast it instead of boil it in the pot. I know roasting it might sound like a lot of work but it’s actually pretty easy.
  
  After you slice of the top, you cut in half, clean out the seeds, rub it with a little bit of oil and then bake it in the oven face down on a baking sheet lined with parchment paper for about 45 minutes.


Holiday Soup: Roasted Acorn Squash Soup with Sage and Sour Cream - Family Spice


  To make the flavors of this soup pop some more, I roasted the acorn squash instead of just sautéing them or boiling them in broth. I also added some carrots – hello, even more beta carotene! After the veggies were browned from roasting, I added it to my pot of sautéed onions and poured in some vegetable broth.
It is easy to create a little oven on your range top in a pan with a lid. 


simply cook on low heat with a well-fitting lid on the pan (I use a glass lid so I can see the food). 
if you want to steam the food for part or all of the cook, just add a little water to the pan
for the ultimate stove-top oven, put your food on a small rack to raise it off the pan's surface so it will get much less direct heat (see photo below).


If you want to caramelize the squash you can do so using options 1 or 3 above very easily.  Directly on the heat will be faster but more aggressive, and you'll probably want to use a little oil or other fat. Let it brown on one side and then turn it over. Depending on the thickness of the cut you may want to turn it more frequently so it cooks through tender by the time it's browned on both sides. 

Put it on a rack on lower heat if you want a longer bake time, more gently like an oven. This is an especially good method if you want to bake it dry with no fat.
