How do I store leftover Sausage and Pepper Keto Frittata?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven; egg- or grain-based items may need a splash of milk or water to refresh texture. Cold-served items (overnight oats, smoothies) keep 2–3 days in the fridge.

Can I substitute ingredients in Sausage and Pepper Keto Frittata?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Sausage and Pepper Keto Frittata for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

Is Sausage and Pepper Keto Frittata keto?
