why this breakfast casserole is a literal life saver

man, I am dra-matic... ok maybe it won't actually save your life but it will save you some time and wasted produce which in this economy comes very close.

• Fridge Clean-Out Approved – If you have eggs and literally anything else, you can make a breakfast casserole. No rules, just vibes.

• Meal Prep Heaven – Make it once, eat all week. That’s a win.

• High-Protein, Nutrient-Packed – Between the eggs, sausage, and veggies, you’re getting a solid meal that won’t leave you starving an hour later.

• Customizable AF – Swap out ingredients based on whatever is dying in your fridge

breakfast egg casserole: the ultimate fridge clean out meal

INGREDIENTS

• 8 large eggs

• ½ cup milk (or dairy-free alt)

• 1 Japanese sweet potato, thinly sliced (because they’re slightly sweet and caramelize beautifully)

• ½ lb sausage, cooked and crumbled (pork, turkey, or plant-based—live your truth bacon also works)

• 1 cup heirloom tomatoes, chopped (cherry tomatoes work too!)

• 1 cup fresh spinach (because we’re pretending to be health-conscious)

• ½ cup crumbled feta (adds that salty, tangy kick)

• 1 tsp garlic powder

• ½ tsp salt + ½ tsp black pepper

• ½ tsp smoked paprika (optional, but highly encouraged)

let's casser-roll

this is MY version of the recipe but as I have stated feel free to swap out my choices for whatever you have in your fridge.

• preheat & prep: set your oven to 375°F and grease a 9x13 baking dish.

  
  

• roast the sweet potatoes: peel & chop the sweet potato and roast it in a baking dish with avocado oil, salt, pepper, garlic powder & sweet potatoes. bake for 20 minutes.

  
  

• cook the protein: I used ground breakfast sausage and cooked it in the skillet until cooked all the way through.

  
  

• whisk the eggs: In a bowl, whisk together eggs, milk, salt & pepper. Pour it evenly over the casserole, making sure everything is coated.

  
  

• assemble the casserole: pull the sweet potatoes out of the oven. layer down spinach, then add in heirloom tomatoes and sausage. mix everything together and add in feta cheese on top

  
  

• bake to perfection: pop it in the oven for 40-45 minutes, or until the eggs are set and the top is slightly golden. Let it cool for about 5 minutes before slicing.

  
  

• eat right away or store for future: if you want to meal prep this for breakfast you can keep them in an airtight container and store in the fridge.

  
  

• reheating: I slice it up and bake in the oven, toaster oven or even the air fryer.
