Introduction

The savory pie, or quiche, is a cornerstone of comfort food cuisine worldwide. Yet, for those following a ketogenic (keto) or low-carb diet, it often presents a major challenge due to its traditionally flour-heavy crust. This Keto Beef, Cheese, and Tomato Pie recipe offers an elegant and delicious solution. It replaces the conventional crust with a low-carb base (almond or coconut flour-based) and eliminates the starch-rich thickeners in the filling, all while retaining an incredibly rich flavor and creamy texture.

The combination of well-seasoned, tomato-infused ground beef and a rich egg and heavy cream custard creates a symphony of umami flavors, making this pie highly satiating and macro-nutritious. It is the perfect dish for meal preparation, as it cuts well and reheats easily, proving that a ketogenic lifestyle does not require sacrificing culinary satisfaction.

Ingredients

To succeed with this pie, the quality and preparation of each ingredient are essential, particularly to guarantee the stability of the filling in the absence of traditional flour thickeners.

For the Beef Filling (The Umami Foundation):

• 500g (1 lb) **Ground beef or minced beef**: Using ground beef with 15% to 20% fat content is recommended for flavor and juiciness, a key factor given the absence of starchy binders.
• 1 **Onion**, finely chopped: Ensures the aromatic base.
• 2 cloves **Garlic**, minced: To be briefly sautéed to maximize flavor.
• 2 tbsp **Tomato paste**: Crucial for umami depth.
• 1 can (14.5 oz) **Diced tomatoes** (undrained): Provides the necessary acidity and moisture for the sauce.
• 1 tsp **Dried Italian herbs** (or rosemary/thyme for infusion): To tie the flavors together.
• **Salt and pepper** to taste.
• 1 tbsp **Olive oil or butter**.

For the Cheese Custard (The Keto Binder):

• 3 large **Eggs**: The structural ingredient that coagulates and sets the pie during baking.
• $1/2$ cup **Heavy cream**: Adds richness and prevents the eggs from becoming rubbery.
• 1 cup **Cheddar cheese**, shredded (plus extra for topping): A reliable melting cheese for flavor.
• $1/4$ tsp **Salt and black pepper**.

For the Crust (The Keto Base):
