Prep the apples: Core and slice 3–4 apples into thin wedges or small chunks.
Thinner slices cook faster. Peeling is optional.
Warm the skillet: Set a large skillet over medium heat. Add 1–2 tablespoons butter and let it melt until foamy.
Add apples and season: Stir in the apples, 1–1.5 teaspoons cinnamon, a pinch of salt, and 1–3 tablespoons sweetener.
Start with less sweetener and adjust later.
Quick steam (optional): Add 1–2 tablespoons water, then cover for 1–2 minutes to jump-start softening.
Sauté and stir: Uncover and cook, stirring every minute, for 5–7 minutes until the apples are tender but not mushy. Lower the heat if browning too fast.
Finish with flavor: Turn off the heat. Stir in 1/2 teaspoon vanilla and 1–2 teaspoons lemon juice if using.
Taste and adjust cinnamon and sweetness.
Serve: Spoon warm apples over oatmeal, pancakes, yogurt, or ice cream, or enjoy them straight from the pan.
