Ingredients
- 12 slices nitrate free bacon sugar free for Whole30
- 2 large sweet potatoes peeled and sliced into thin rounds approximately 1/4"
- 1 tbsp melted cooking fat** + sea salt for roasting the sweet potatoes
- 3 cups Brussels sprouts tops removed and either quartered or chopped, plus about 1 tbsp cooking fat** plus a pinch of sea salt for roasting
- 1 large onion or 2 small sliced thin
- 12 eggs
- 1/3 cup full fat coconut milk
- 1/2 tsp salt plus to suit your taste
- 1/4 cup nutritional yeast this is for a cheesy flavor, you can also sub Parmesan if you include dairy in your diet
- 1/2 tsp garlic powder
- Black pepper to taste
Instructions
-
Preheat your oven to 425 F and grease a 9x13" casserole dish with coconut oil, and line a large baking sheet with parchment paper.
-
Cut the bacon into 1" pieces and cook in a large heavy skillet, over medium high heat, stirring occasionally for even browning, until crisp. Remove with a slotted spoon to drain on paper towels and set aside. Reserve at least 3-4 tbsp of bacon fat to caramelize onions.*
-
Next, roast the sweet potatoes and brussels sprouts. Toss the sweet potato rounds with cooking fat of choice and sea salt to taste (I add a generous pinch) and arrange, (overlapping since they will shrink after roasting) over the bottom of your casserole dish.
-
Arrange the brussels sprouts on the parchment lined baking sheet in a single layer. Place the casserole dish and baking sheet in your oven to roast. The sweet potatoes will roast for about 30 minutes until soft and the brussels sprouts for about 20.
-
Meanwhile, caramelize the onions. Heat the pan you cooked your bacon in over low/medium heat and add the onions, tossing with the leftover reserved bacon fat*
-
Add a pinch of salt, and cook, stirring occasionally, adjusting the heat if any onions begin to brown too quickly. Cook the onions long and slow (about 25 minutes) to bring out the most flavor. Once the onions are deeply caramelized and very soft, remove from heat.
-
While the onions cook, whisk together the eggs, coconut milk, nutritional yeast, salt, pepper, and garlic powder.
-
Lower your oven heat to 400 F, then assemble the casserole. Layer your roasted brussels sprouts over your sweet potato rounds in the casserole dish. Remove the caramelized onions with a slotted spoon and layer over the brussels sprouts, follow with the cooked bacon. Finally, pour all the whisked egg mixture over the casserole to evenly cover.
-
Bake in the 400 F oven for about 25 minutes until the center is just set and edges begin to turn light brown. Allow to cool for a bit in the baking dish before cutting into pieces and serving warm. Leftovers can be stored, covered, in the refrigerator for up to 5 days*** Enjoy!

Recipe Notes
*If you want to use a different cooking fat to caramelize the onions, coconut oil or ghee are your best bets!
**Melted coconut oil, ghee, or light-flavored olive oil will work well here
***If you wish to freeze this casserole to make ahead of time, cover tightly and freeze before the final baking step.
