Breakfast Casserole with Spaghetti Squash

Breakfast CasseroleI love breakfast, and I am always looking for ways to incorporate more variety. I like eggs, and I LOVE bacon but, what about veggies??  This recipe is a great way to get veggies into your family’s diet and I promise, no one will complain! (Looking for more breakfast recipes and ideas?? Check out THIS blog post!

Cook the spaghetti squash the day before or even prepare the entire casserole a day ahead, and throw it in the oven when you wake up! Also consider making this easy casserole during the weekend to enjoy for breakfast during the busy mornings ahead.

I have a traditional Breakfast Casserole in my first cookbook, Satisfying Eats,  but I wanted to use my new favorite veggie in a recipes besides a pasta substitute!  The result is a savory casserole that kinda reminds me of a hash brown casserole with sausage! YUM!

How to cook a Spaghetti Squash


Spaghetti squash is probably one of the most misunderstood vegetables. Most people don’t eat it because they don’t know how to cook it, or they are afraid to cut the squash. And guess what?? You SHOULD be scared to cut an uncooked spaghetti squash. Instead of cutting it in half and heating up my entire house cooking it in the oven, I experimented cooking the hard yellow squash in the slow cooker, and it worked perfectly!

For the full tutorial, be sure to check out out my blog post here! To preserve the great texture of the spaghetti squash for this recipe, I actually cooked the squash for only 2 hours and 15 minutes on high in my slow cooker. Whatever you do, DO NOT overcook it or you will have spaghetti mush… not good!

NOTE: While the spaghetti squash is cooking, if you see through the lid that the “skin” has busted, feel free to go ahead and turn the slow cooker off and remove the lid (so that it doesn’t continue to cook). The key is NOT overcooking!  Cooking time will vary based on the slow cooker you use. If a knife can be inserted into the skin of the spaghetti squash, it is done.


Shortcuts in the Kitchen

I confess… I am lazy… well, I am BUSY like most of you are I am sure! Over the past year, I have had my hands full with two cute little boys. In some ways, it is easier now that my youngest is one years old, but in other ways, it’s even harder! Now I have 2 little ones to keep out of harm’s way, feed, bath, love …. My cup runneth other! I love my little guys and I love cooking for them, however, I am experimenting with ways to cut my cooking time down to a minimal, and cutting my dirty dishes down as much as possible. I feel like I spend ALL DAY in the kitchen and I would rather spend it with my boys.

One of my favorite shortcuts has been using more frozen veggies. I will use fresh when in season but for the rest of the time, frozen is the way to go! My freezer is stocked with diced onions, bell peppers, green beans, broccoli, spinach and sliced carrots. Having these veggies in the freezer has really cut my prep and cooking time down significantly! Also, no more cutting before I can start cooking which also means no dirty knife or cutting board!

I have also determined that frozen veggies cook quicker than fresh. Freezing vegetables breaks down the cell walls which sounds like a bad thing but for me, it’s not. This just speeds up the cooking time! 

You can use fresh onions and bell pepper in this recipe but save yourself a little time and get the frozen!

Breakfast Casserole 2Variations

  • Use any vegetable you like or have on hand such as sliced carrots, fresh or frozen spinach, sauteed zucchini… really, the possibilities are endless!
  • Use any meat. I chose to use breakfast sausage but you can also use leftover diced ham or cooked and crumbled bacon. (I used my Breakfast Sausage recipe from my cookbook, Comforting Eats.)
  • Use whatever cheese you prefer. I LOVE Cabot’s Extra Sharp Cheese… absolutely delicious! I like Kerrygold’s cheese is delicious, but it’s not always in my budget!
  • Need to feed a LOT of people?? Simply double the recipe and use the entire spaghetti squash. Cook the casserole until the center is set and the cheese on top has browned. 
  • Omit the sausage and this casserole will be a great side item at any meal.
  • Can’t have nuts?? Use 1 tablespoon of coconut flour instead of almond flour. This is used to absorb the extra liquid from the spaghetti squash.

I hope you enjoy this recipe and you come to LOVE spaghetti squash as much as I do! Keep you eye out for more recipes using this unique vegetable!

Tell me, what do you think about spaghetti squash?? Love it or leave it??

    Had to write and say that I made the Breakfast Casserole this morning and it is LUSCIOUS! It smelled SO good cooking, it was hard to wait for it to cool off enough to dig in. I give it my highest rating!!! I’m single and it should provide at least five or six generous meals – may have it for dinner some nights. Thank you, thank you for all you do!!!

  2. Brandy Campbell says

    AMAZING! Even my daughter that “hates” breakfast food gobbled it up AND got seconds!!

  3. Jessica says

    This is probably a silly question, but when you say “blend well” do you mean using a blender? Or just combining the ingredients by hand? Thanks!!

    • satisfyingeats says

      Jessica, not a silly question. Just use a spoon to make sure all ingredients are incorporated evenly. Enjoy!

    This casserole was sooooo good! It reminded me of good ‘ol southern hashbrown casserole, except without all those carbs. So rich and creamy and the speghetti squash really added that potato texture.
    I added zuchinni which was really really good. I also doubled it and me and my husband alone still polished off the whole pan in 2 days! Thanks!!

  5. says

    I loved this! I am looking forward to trying many of your other recipes! I halved the recipe so I could try the Cajun Spaghetti recipe too.
    We mentioned the recipe on our radio show this morning and will post a link to your page. Thanks!!

  6. Jane says

    Wow this is absolutely delicious! First time to make spaghetti squash–thanks for the great tip of the crockpot! Looking forward to using the leftovers for a quick breakfast or packing for my lunch!

    Just made your Breakfast Casserole today… DELISH!! Thank you so very much! In an effort to save time baking the squash, I washed it, forcefully pierced it in about 15-18 places, and placed in microwave (our microwave is 950 watts) for 15 minutes. It came out perfect – not overdone and not underdone.

    Thank you again for your wonderful recipes.

    Warm regards,
    K J
