In a mixing bowl, whisk to combine the flour, sugar, instant yeast, salt, basil, and garlic powder. Set aside.
In a small bowl, mix the tomato paste into the warm water until it’s dissolved. Add this to the flour mixture, and mix until the dough starts to come together (it’s okay if there’s still a little dry flour visible).
Mix in the chopped sundried tomatoes.
On a lightly floured surface, knead the dough for about 5 minutes by hand (or about 3 minutes in a stand mixer with a hook attachment), until the dough is smooth and elastic.
Spread a little oil from the jar of sundried tomatoes in the mixing bowl that had the flour mixture. Place the dough in the oiled bowl. Cover with a clean kitchen towel and set in a warm draft-free place to rise and double in size, after about 1 to 2 hours.
On a lightly floured surface, shape the dough into a round or oval shape. Use your hands to gently push the sides of the dough underneath itself, to create tension on the top.
Place the dough seam-side-up either in a proofing basket or in a shallow bowl lined with a kitchen towel. Cover the dough again with a towel and allow it to proof for 30 minutes.
While the dough is proofing, preheat your oven to 425°F. Place a Dutch oven with the lid in the oven to become hot as the oven preheats.
Once the oven is preheated, carefully remove the Dutch oven and remove the lid. Sprinkle a little flour or cornmeal on a large piece of parchment paper and place the dough on top seam-side-down. Pick up the bread by holding the corners of the parchment paper, and carefully place it in the hot Dutch oven.
Cover with the lid on and place it in the oven. Bake covered for 30 minutes. Then remove the lid, and bake for an additional 10 to 15 minutes uncovered, until the crust is brown and crispy. Allow the loaf to cool on a cooling rack for at least 1 hour before slicing. Enjoy!!
