Add all of the ingredients to the bowl of an electric stand mixer except for the milk. Using the dough hook attachment, mix on lowest speed for about 1 minute.
3 cups all-purpose flour, 4 Tablespoons melted butter, 1½ teaspoons instant yeast, 1 Tablespoon granulated white sugar, 1½ teaspoons kosher or fine grind sea salt
Add in half of the milk and mix on the lowest speed until the mixture starts to come together. It will look dry and crumbly at this point. Add half of the remaining milk and mix on low until a shaggy dough ball has formed. It will start out looking dry and as it mixes the flour will absorb the milk and become more hydrated.
1 cup whole milk
When a shaggy dough ball has formed, add in the remaining milk 1 Tablespoon at a time and mix on Speed two. The dough is perfectly hydrated and ready to use when it becomes a smooth ball and about half dollar size of it is sticking to the bottom of the mixing bowl. You may not use all the milk and you may need a little more depending on the flour and humidity. Go by looks of the dough and you will have perfect bread. This kneading process on speed two will take 5-10 minutes.
First Proof of the Dough
Once the dough is ready, form it into a ball or disc. Lightly butter the bottom of the Ninja Combi pan or a large mixing bowl and place the dough in the bottom. Ninja Combi: Proof directly in the Combi pan on 95℉/35℃ for 45 minutes or until doubled in size. Room Temperature: Proof in covered mixing bowl until doubled in size. This can take 60-90 minutes.
Shaping and Second Proof
Once the dough has doubled in size, remove it from the bowl or pan and press it out on clean work surface into a rectangle that is about 10" wide by 8" long. I don't usually have to flour the work surface, but you can if needed. If this is the first time you have shaped dough for a loaf of bread, I recommend you watch the video in the post.
Fold the top third of the dough towards the middle and press away from you to form tension and start to form a log shape. Tuck in the sides and then bring the bottom of the dough that is closest to you up to the middle to finish the log shape. Pinch the seams together and place the dough into the buttered loaf pan.
Ninja Combi: Place the loaf pan directly into the Combi pan. You do not want to use a rack because it will put the bread too close to the heating element. You can add the ½ cup of water now or after the second proofing and before baking. Select the proof function and set the temperature to 95℉/35℃ and the time for 30 minutes. When the second proofing is done, score the bread down the middle with a sharp knife or bread lame about ½" deep. Room Temperature: Loosely cover the loaf pan and let it sit in a warm place for 45-60 minutes or until the dough just starts to rise over the lip of the loaf pan.When the second proofing is done, score the bread down the middle with a sharp knife or bread lame about ½" deep.
Baking in the Ninja Combi
Make sure you have ½ cup water in the bottom pan and the loaf pan is sitting directly in the Combi pan. It's fine that it is sitting in the water. Select the CombiCrisp function and set the temperature to 325℉/160℃ and the time for 30 minutes. HIt start. It will steam for a short time and then the countdown will start. When the time is up remove the loaf pan and proceed to the cooling phase.
Baking in a traditional oven
Preheat the oven to 375℉/190℃. Place the loaf pan on the middle rack and bake at 375℉/190℃ for 35-40 minutes or until golden brown on top and it should sound hollow when you tap on it.
Buttering & Cooling
When the bread is done, remove the loaf pan from the oven or Ninja Combi and turn it over onto a cooling rack to remove the loaf of bread. Liberally butter the outside and wrap in a tea towel or flour sack to cool. This will soften the crust for the perfect sandwich bread. Allow to cool completely before slicing.
