Beef Pho Soup

Gather all necessary ingredients and materials beforehand.\nPreheat your oven to 425 degrees Fahrenheit (220 degrees Celsius). This high temperature will help bring out the best flavors in your dish.\nPlace beef bones on a baking sheet and roast them in the preheated oven until they are nicely browned, taking about 1 hour to achieve this. The browning process is crucial for adding depth to your broth.\nOn a separate baking sheet, place onion halves and roast them until they are blackened and soft, requiring about 45 minutes. This step is essential for developing the rich flavors in your broth.\nTransfer the roasted beef bones and onion halves to a large stockpot. Add some essential spices like ginger, salt, star anise, fish sauce, and 4 quarts of water. Bring the mixture to a boil, then reduce the heat to low and let it simmer for 6 to 10 hours. The longer you simmer, the more flavorful your broth will be.\nStrain the broth into a saucepan and set it aside for later use. This step is crucial in separating the solids from the liquid, resulting in a clearer broth.\nSoak rice noodles in a large bowl filled with room temperature water for 1 hour. This step helps to rehydrate the noodles, making them easier to cook.\nAfter 1 hour of soaking, heat up the reserved broth by bringing it to a simmer. This will help to warm it up and make it easier to cook the noodles.\nBring a large pot of water to a boil, then cook the noodles in it for 1 minute. Drain the noodles and set them aside.\nDivide the cooked noodles among 4 serving bowls, then top each bowl with sirloin, cilantro, and green onion. Ladle hot broth over the top of each bowl, making sure to cover all the ingredients.\nLet the dish sit for 1 to 2 minutes, allowing the beef to partially cook and lose its pink color. This step is essential in ensuring that your beef is cooked safely.\nServe the dish with bean sprouts, Thai basil, lime wedges, hoisin sauce, and chile-garlic sauce on the side. These accompaniments will add a nice contrast to your dish and enhance its overall flavor profile.
