My mom taught me you don't need an oven for fresh loaves. Just 4 ingredients for bakery-quality results.

Carefully lift the rested dough by picking up the edges of the parchment it is sitting on, and transfer the whole parchment-and-dough bundle into the parchment-lined slow cooker. Adjust the parchment so the dough sits centered in the cooker.
Cover the slow cooker with its lid, set it to HIGH, and cook for 2 to 2 1/2 hours. The bread is done when the top feels firm and dry, the sides are lightly browned, and the internal temperature in the center reads about 200°F on an instant-read thermometer.
For a deeper, crustier top like a bakery loaf, once the bread is cooked, lift it out by the parchment and place it (still on the parchment) under a preheated broiler in your oven for 3–5 minutes, just until the top is a deeper golden brown and nicely cracked. Watch closely so it doesn’t burn. This step is optional but gives that classic crusty finish.
Transfer the bread to a wire rack and let it cool at least 30 minutes before slicing or tearing. This resting time helps set the crumb so you get that soft, airy interior without it turning gummy.
Variations & Tips
For a heartier flavor, you can swap 1 cup of the all-purpose flour for whole wheat flour; just be aware the loaf will be a bit denser, but still very good. If your kitchen is chilly, let the dough rise in a slightly warm spot—near (not on) a warm appliance, or in an oven that’s been turned off but had the light left on. To add a little character, stir in 1 teaspoon of sugar or honey with the warm water for a slightly more browned crust and a hint of sweetness. For a country herb loaf, gently knead in 1–2 teaspoons of dried herbs (like rosemary, thyme, or Italian seasoning) when you first mix the dough. If you prefer a chewier crust, skip storing the bread in plastic; instead, keep it loosely wrapped in a clean kitchen towel once it has cooled. Leftovers can be revived by toasting or warming slices in a dry skillet. This same method works well on busy days: mix the dough at night, let it rise while you sleep, and cook it in the slow cooker the next afternoon so you have a fresh, crusty loaf waiting for supper, just like my mom used to time it around chores and evening meals.
