In a large mixing bowl, combine 1 1/2 teaspoons instant dry yeast, salt, and warm water (100°F–110°F). Stir until the yeast is dissolved.
Add 1 3/4 cups of all-purpose flour to the yeast mixture. Stir until a rough dough forms. Knead the dough for about 5–7 minutes, slowly adding more flour as necessary until smooth and elastic. It should be soft and tacky, but not sticky enough to stick to your hands.
Cover the bowl with a clean kitchen towel or plastic wrap and let the dough rise for 1 hour, or until it has doubled in size.
Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
Shape the dough into a smooth, round loaf. Flatten it slightly to allow for a surface area to put your toppings on.
Sprinkle 1/4 cup shredded cheddar cheese evenly over the top of the dough. Pile the sliced jalapeños on top pressing them gently into the dough. They will spread out with the dough as it bakes. You can add additional shredded cheddar cheese on top of the jalapenos as well.
Bake in the preheated oven for 20–25 minutes, or until the cheese is melted and golden brown.
Remove from the oven and allow the bread to cool slightly before slicing and serving.
