Spicy Spaghetti Squash Casserole

Spicy Spaghetti Squash Casserole is a super flavorful spicy smooth-but-a-little chunky. It’s just as good the next day and is even good cold.

I think I just invented this one, and it magically turned into a keeper. I happened to have a large spaghetti squash so I began exploring casseroles for yellow squash. I specifically did not want to make a vegetable version of spaghetti. Been there, done that; and I’m often underwhelmed with the result.

I deliberately overcooked the squash; I did not want the strands that spaghetti squash is known for. I was very pleasantly surprised with the result – when I took it out of the oven and scooped it out of the shell, it was mush. Spaghetti squash  happens to have a very nice flavor all by itself. This casserole has a nice texture for what is essentially a vegetable custard dish (ie, with eggs and milk). It is a little lumpy and very flavorful – I love the heat and flavor the chiles provide. Plus the sharp cheddar really adds a special depth to the flavor.

Note: in the photo, I used Buffalo seasoned Panko bread crumbs. You can use saltines, Ritz crackers, Panko crumbs, crushed tortilla chips – just about any will work. This is a very versatile and forgiving recipe.

You literally cannot taste or see the sharp cheddar cheese at all. It adds quite a bit to both flavor and texture. That makes it a secret ingredient! This would not be the same dish without it.

I hope you try it – enjoy!
