Ingredients:
- 1 Tbsp Unsalted Butter
- 450 g (1 lb) Breakfast Sausage Meat (ground pork)
- 1/2 medium Yellow Onion, finely diced
- 1/2 medium Red Bell Pepper, finely diced
- 2 cups, packed Fresh Spinach, roughly chopped
- 1 cup Sharp Cheddar Cheese, shredded
- 1/2 cup Monterey Jack or Mozzarella, shredded
- 12 Large Eggs
- 1/2 cup Heavy Cream (Double Cream)
- 1 tsp Dijon Mustard (Optional)
- 1 tsp Salt
- 1/2 tsp Black Pepper, freshly ground
- 1/2 tsp Dried Italian Herbs
Instructions:
- Sauté the Meat: Heat butter in a frying pan over medium-high heat. Add the sausage meat and break it up. Cook until fully browned and drain off any excess grease.
- Sauté Aromatics: Add the diced onion and red pepper to the pan. Cook with the sausage for 3–5 minutes until softened. This step concentrates the flavor and removes excess moisture.
- Wilt the Spinach: Remove the pan from the heat. Stir in the chopped spinach until it just wilts. Set the mixture aside to cool slightly.
- Combine Wet Ingredients: In a large mixing bowl, thoroughly whisk the 12 large eggs until light and frothy.
- Season: Whisk in the heavy cream, Dijon mustard, salt, pepper, and dried herbs until fully combined.
- Layer the Slow Cooker: Grease the slow cooker bowl (or insert a liner). Spread the cooled sausage/vegetable mixture evenly across the bottom.
- Add Cheese: Sprinkle three-quarters (3/4) of the mixed shredded cheese evenly over the top of the sausage mixture.
- Pour the Custard: Carefully pour the whisked egg mixture over the contents, ensuring the solids are submerged.
- Top: Sprinkle the remaining cheese over the top.
- Seal and Manage Condensation: Place a clean, folded kitchen tea towel directly over the rim of the slow cooker bowl before securing the lid. This crucial step absorbs condensation and prevents a soggy casserole.
- Cook: Set the slow cooker to LOW for 3.5 to 4 hours, or HIGH for 2 to 2.5 hours. Do not lift the lid during the first 3 hours.
- Test for Doneness: The casserole is finished when the edges are set and puffy, and the center is mostly firm (internal temperature should reach 165°F / 74°C).
- Rest: Turn the slow cooker off and leave the lid (and tea towel) on for 15 minutes to allow the casserole to fully set before slicing and serving.
