Why These Ingredients? The Intelligence Behind the recipe
This frittata isn’t just food—it’s fuel. Every ingredient plays a role in gut health, nutrient absorption, and overall well-being.
Pasture-Raised Eggs (8 large eggs) – A complete protein source rich in choline (essential for brain health), omega-3s, and lecithin, which helps digest fats and support liver function.
Lard (2 tbsp, from pasture-raised pigs) – An excellent heat-stable fat loaded with vitamin D and anti-inflammatory properties. Supports digestion and healthy gut lining.
Red Onion (½ cup, finely chopped) – Packed with quercetin, a potent antioxidant, and prebiotic fiber, which feeds beneficial gut bacteria.
Asparagus (½ cup, chopped) – A top source of inulin, a prebiotic fiber that helps nourish gut bacteria and aids digestion. Also high in folate, supporting cellular repair and detoxification.
Mushrooms (½ cup, sliced) – Contain beta-glucans, which support the immune system and help regulate gut bacteria for a balanced microbiome.
Fresh Spinach (2 handfuls) – Loaded with magnesium, which helps relax the digestive tract, along with fiber to support regularity.
Tomatoes (½ cup, sliced) – Rich in lycopene, a powerful antioxidant that supports heart health and reduces inflammation. Cooking tomatoes enhances their lycopene content, making this frittata even more beneficial for overall health.
Grass-Fed Cheese (½ cup, optional) – A probiotic-rich food (if raw or aged), which supports gut health and strengthens digestion.

Ingredients
(Makes 6–8 servings)
8 large pasture-raised eggs
½ teaspoon sea salt
¼ teaspoon freshly ground black pepper
2 tablespoons lard (or butter)
½ cup red onion, finely chopped (or scallions)

Instructions
Step 1: Prepare the Eggs
Crack the eggs into a large Pyrex jug, season with salt and pepper, and whisk until fully combined. Set aside.
Step 2: Sauté the Vegetables
Heat a cast iron skillet over medium heat and melt the lard. Add the red onion, asparagus, and mushrooms, stirring occasionally. Cover the skillet with a lid and let the vegetables sweat until they become tender, about 5 minutes.
Step 3: Add the Spinach
Once the vegetables are soft, add the fresh spinach and cook for another 2–3 minutes, until wilted.
Step 4: Pour in the Eggs
Evenly spread the vegetables across the pan and pour the whisked eggs over them. Let the mixture cook for a couple of minutes, gently tilt the pan to ensure even distribution of ingredients, but try not to scrape across the bottom of the pan to prevent ingredients sticking.
Step 5: Bake the Frittata
Add the sliced tomatoes to the top of the pan and If using cheese, sprinkle it over the top now. Then, transfer the cast iron skillet to a preheated oven at 375°F (190°C). Bake for 10–15 minutes, or until the eggs are fully set and the top is slightly golden.
Step 6: Cool & Store
Remove from the oven and let it cool for a few minutes before slicing. You can serve it immediately or let it cool completely, then store it in the fridge for up to 5 days.

After step 3, if the lard has been soaked up or the vegetables feel sticky add an extra knob of lard and allow it to melt in the bottom of the pan before adding the eggs. This will prevent the frittata sticking to the cast iron pan while in the oven and make serving much easier after cooking.
You will notice that your frittata is fully cooked when the egg mixture starts to pull away from the sides of the pan.
