  • Place casserole in pressure cooker. Cook for about 8 minutes once pressure builds. After cooking, perform a slow release of pressure.
  • Carefully lift the lid once the float valve drops. Let cool slightly before serving.

Notes

Start by pre-cooking the squash in a pan rather than boiling it to reduce moisture. Drain canned tomatoes well to prevent sogginess. Use sharp cheddar cheese for best flavor. Slice squash thinly for even cooking. Use a slow pressure release to keep squash tender but not mushy. Leftovers keep well in fridge for 3-4 days or frozen for up to 1 month.
