Rich, flavorful beef pho that you can customize with your favorite ingredients.
For the broth:
2 lbs marrow bones
2 lb oxtail
Primal Kitchen Avocado Oil Spray
1 onion, cut into quarters
3 green onions
2 inch piece ginger, cut into thick slices
4 cloves garlic
1 tsp. coriander seed
1/2 tsp. black peppercorn
1 cinnamon stick
1–2 star anise
1/4 cup coconut aminos
1/2 tbsp. coconut sugar or 1–2 carrots
Optional: 1-2 Tbsp. fish sauce
6–7 cups water
1/2–1 lb. very thinly sliced top sirloin
Noodle of choice: shirataki noodle, kelp noodles, zucchini noodles, rice noodles
Herbs: mint, basil, cilantro
Thinly sliced vegetables like daikon radish and/or carrot
Sriracha, fish sauce, coconut aminos, red pepper flakes limes
Preheat your oven to 425 degrees. Lay your marrow bones and oxtail on a sheet pan. Roast for 20 minutes, then flip them over and roast for an additional 20-25 minutes.
On a second tray, toss the onion, green onions, garlic and ginger in a spray of avocado oil. Roast for 15-20 minutes.
In a small skillet, toast the coriander, peppercorns, cinnamon and star anise for about 1 minute over medium heat, or until fragrant.
Once the bones and vegetables are roasted, place them all into an instant pot. Add the toasted spices, coconut aminos, and coconut sugar. Pour in 6-7 cups of water, or until the liquid is halfway between the ½ and ? fill lines. Secure the lid on the Instant Pot and set it to the Soup/Stew Function. Set the Instant Pot to high pressure for 1 hour 45 minutes. After the pot finishes cooking and beeps, allow it to naturally release for 20 minutes. Allow the broth to cool slightly, then strain the broth into containers. Reserve any meaty bits from the oxtail for the soup or other purposes.
At this point, you can either refrigerate the broth to let the fat separate from the broth, or immediately use it. If you refrigerate, refrigerate overnight and pick off the fat layer that forms at the top of the broth. Place the broth in a pot and bring it to a boil. Allow it to simmer for a few minutes.
Very thinly slice your beef. You may find it easier to freeze the piece of beef for a few minutes to help it firm up and be easier to slice. Traditionally, you pour the hot broth over the beef which partially cooks it, but you can also place the beef into the simmering soup for a short amount of time to cook it more if you’d like. Arrange your bowls with your beef, noodles of choice, and any other add ins, such as cilantro, basil, mint, daikon radish, and scallions. Feel free to add in any red pepper flakes, sriracha, coconut aminos or fish sauce to taste.
This broth is made in an instant pot to save time. You can also make it on the stovetop. If cooking on the stovetop, allow the broth to simmer for 8+ hours. When the vegetables start to fall apart, remove them from the broth to prevent them from making the broth cloudy.
For the noodles, you can use shirataki or kelp noodles for low carb options, or even zucchini noodles. You can also use thin rice noodles.
