Ingredients and substitutions

• 1 tablespoon vegetable oil. I use avocado oil. Any vegetable oil is fine. You can skip the oil if you are not eating a high fat keto diet as the vegan sausage will express some fat.
• 14 oz vegan sausage. I used Beyond Meat Hot Italian sausage. Any brand of sausage or beef substitute would work.
• 2 tablespoons fresh herbs. I love smoky herbs in the casserole so I used a mix of sage and oregano. Thyme and rosemary are great too. You can substitute with 2 teaspoons of dried herbs.
• 4-5 cups fresh greens. I used Swiss chard. Use any greens of your choice, including spinach, kale or mixed spring greens.
• 14 oz extra firm or super firm tofu. Either is fine. Soft tofu will create a runny filling so use extra firm or super firm for the right consistency to the casserole.
• 1 teaspoon garlic powder + 1 teaspoon onion powder (or flakes)
• 2 tablespoons nutritional yeast
• 1 teaspoon dried oregano. Substitute, if you wish, with another savory herb of your choice like thyme, sage or rosemary.
• 1 cup vegan heavy cream. Or use soymilk as a substitute.
• Salt and ground black pepper to taste. You can also use red pepper flakes for a bit of an added kick.
• 1 cup vegan cheddar cheese shreds

How to make the vegan low carb breakfast casserole

• Preheat the oven to 400 degrees Fahrenheit/200 degrees Celsius.
• Make a smooth tofu cream by blending the tofu, garlic and onion powders, nutritional yeast, dried oregano, salt, pepper and heavy cream along with ½ cup water.

• Heat oil in a 10-inch cast iron skillet or any oven-safe 10-inch skillet. (If you don't have an oven-safe skillet, you can transfer the sausage-veggie mixture to a lightly oiled, 9- or 10-inch oven-safe baking dish before adding the tofu cream).
• Add the crumbled vegan sausage to the skillet and saute a couple of minutes until it begins to brown.
• Stir in the herbs. Then add the greens (finely shredded) to the skillet. It will look like a lot when you add them but they will quickly wilt down. Saute the greens until they have wilted down.

• Stir in ½ cup of the vegan cheddar cheese shreds, reserving the rest for the top. Season with salt and ground black pepper or red pepper flakes as needed.
• Turn off the heat and stir in the tofu cream (if not using an oven safe skillet pour the filling into the prepared baking dish at this point, then stir in the tofu). The tofu cream will be thick. Use a ladle to mix it with the sausage and greens.
• Sprinkle the remaining cheddar shreds on the top of the tofu-sausage mixture.

• Bake for 30 minutes. Turn on the broiler in the last 3-4 minutes of baking to get a crispy top. Keep a close eye when you turn on the broiler as the top can burn quickly.
• Wait 10 minutes, then serve hot or warm.
