The way to Make Breakfast Casserole with spaghetti squash
Step 1:
I like to recommend cooking the spaghetti squash and bacon forward of time. Preheat your oven to 400ºF, and for the reason that squash takes the longest to prepare dinner, begin with that.
Minimize the squash in half cross-wise, which means you’ll minimize via solely the middle of the squash the place it’s essentially the most hole. (That is the best strategy to minimize a spaghetti squash, in my view.)
Use a spoon to take away the seeds, then place the halves cut-side-down on a rimmed baking sheet lined with parchment paper. Bake at 400ºF till the squash is tender, about 45 to 60 minutes.
Now that the squash is cooking, organize the bacon in a single layer on one other rimmed sheet pan. Keep away from any overlap for the crispiest outcomes. Prepare dinner the bacon at 400ºF for 20 to 25 minutes, or till it appears crispy. You are able to do this on a second shelf within the oven whereas the spaghetti squash is cooking, to maximise your time.


Step 2:
To prepare dinner the onion, add a drizzle of olive oil to a skillet over medium-high warmth. Let the pan preheat for 1 to 2 minutes, then add the onion and stir usually. Prepare dinner till the onion is tender and translucent, about 6 to eight minutes. Then set it apart to chill.
Subsequent, use a fork to scrape the cooked spaghetti squash strands into a big mixing bowl.(it needs to be cool sufficient to deal with; particularly should you prepped it the night time earlier than.) Then add about 4 strips of crispy, chopped bacon. To make this dish vegetarian, you possibly can omit the bacon.
Switch the cooked onion and half of the shredded cheese to the bowl, too.


Step 3:
Crack the eggs right into a separate bowl, simply to be sure you can scoop any damaged egg shells out simply. Combine within the salt and pepper, and whisk properly with a fork.
Pour the egg combination into the massive bowl and stir properly. Then pour the combination right into a greased baking dish. (I take advantage of a 9-inch by 13-inch baking dish.)
Sprinkle the remaining cheese and any reserved bacon items excessive, then bake at 400ºF for 40 to 45 minutes, or till the highest appears golden and the middle of the breakfast casserole has overrated within the heart.


Serving Suggestions
Take away the pan from the oven and let it cool for 15 to twenty minutes, earlier than slicing and serving. I wish to sprinkle a couple of chopped chives excessive, for a pop of coloration.
Leftovers could be saved in an hermetic container within the fridge for as much as 5 days. It’s such a straightforward breakfast to reheat all through the week!

Let the spaghetti squash and bacon cool, till they’re snug sufficient to deal with. (You do not need to combine the eggs into piping sizzling squash, or they’ll scramble as you stir.

As soon as you possibly can deal with the squash, use a fork to scrape the spaghetti squash strands into a big mixing bowl. Chop 6 to eight items of crispy bacon in to items, and sprinkle them into the bowl, too. (Reserve a couple of bacon items to sprinkle on high, should you like.)

- Diet data is for 1 of 12 slices, assuming you utilize 6 ounces of bacon. This data is robotically calculated, and is simply an estimate, not a assure.
- This recipe was up to date in December 2022, to extend the salt from 1 teaspoon to 1 1/2 teaspoons. In the event you favor utilizing much less salt, be happy to make use of the unique 1 teaspoon, however I believe the flavour is healthier with the additional 1/2 teaspoon addition.
