Creating Roasted Garlic Tomato Spaghettini with Garlic Parmesan Bread Crumbs can be an enjoyable endeavor. Follow these easy steps to ensure your dish turns out superbly:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C). This helps in roasting the garlic perfectly.
2. Prepare the Garlic: Slice the top off the bulb of garlic to expose the cloves. Drizzle a tablespoon of olive oil over it, wrap it in aluminum foil, and place it in the preheated oven. Roast for about 30 minutes or until the cloves are golden and tender.
3. Cook the Spaghettini: In a large pot, bring salted water to a boil. Add the spaghettini and cook according to package instructions until al dente. Once cooked, drain and set aside, reserving a cup of pasta water.
4. Sauté the Tomatoes: In a large skillet, add the remaining olive oil and heat over medium heat. Add the diced tomatoes, salt, pepper, and red pepper flakes. Sauté for about 5-7 minutes until the tomatoes start to break down.
5. Add Roasted Garlic: Once the garlic is ready, let it cool slightly, then squeeze the roasted cloves out of their skins into the skillet with the tomatoes. Stir well to combine and cook for another 2-3 minutes. If the sauce looks too thick, add some reserved pasta water to achieve desired consistency.
6. Mix with Spaghettini: Add cooked spaghettini to the skillet, tossing well to coat the pasta with the sauce. Add in chopped basil and mix until evenly distributed.
7. Prepare Garlic Parmesan Bread Crumbs: In another pan, melt a tablespoon of butter over medium heat. Add fresh bread crumbs and toss until golden brown. Stir in the grated Parmesan cheese, mixing well before removing from heat.
