I just made an Orange Beef Recipe that’s surprisingly bright and messy-in-a-good-way like real takeout but paleo, Whole30, and actually worth bragging about.

Jump to Recipe

I’m obsessed with this Orange Beef Recipe because it hits that sweet-tangy punch I crave without junk. I love the way the citrus cuts through rich meat, especially when I’m using flank steak and fresh orange juice.

It’s not polite food. It’s loud, saucy, and makes takeout feel like a lie.

I adore that it fits Paleo Beef Recipes so I can eat hearty without the usual grain/soy baggage. But mostly I make it because the textures and bright orange flavor make me want to lick the plate.

No guilt. Just really, really good dinner.

Seriously always asking for seconds.

Ingredients

Print Recipe (No Advertisments)

Flank or skirt steak: hearty protein, thin slices stay tender and meaty.
Arrowroot starch: gives crispness on the outside, light and not gummy.
Extra arrowroot or tapioca: thickens sauce without gluten or weird taste.
Coconut aminos: salty-sweet stand in for soy, milder and slightly sweet.
Fresh orange juice: bright, tangy base that keeps the dish lively.
Orange zest: tiny punch of citrus oils, smells amazing and fresh.
Apple cider vinegar: cuts sweetness, adds a subtle tangy backbone.
Fresh ginger: spicy warmth, it wakes up the whole plate.
Garlic infused oil: gives garlic flavor without actual bulbs, AIP friendly.
Coconut or avocado oil: neutral high-heat oil, helps get golden edges.
Fine sea salt: brings out flavors, don’t overdo it — taste first.
Chopped cilantro: fresh herb lift, brightens each bite, adds color.
Orange slices: pretty garnish, extra citrus if you want more zing.

Ingredient Quantities

1 pound flank steak or skirt steak, thinly sliced against the grain

1/3 cup arrowroot starch (for dredging and sauce thickening)

2 tablespoons arrowroot or tapioca, extra for sauce if needed

1/4 cup coconut aminos

1/2 cup fresh orange juice (about 2 medium oranges)

1 teaspoon orange zest, finely grated

1 tablespoon apple cider vinegar

1 tablespoon freshly grated ginger (about a 1 inch piece)

1 tablespoon garlic infused oil (for AIP garlic flavor without the actual garlic)

2 tablespoons coconut oil or avocado oil, for cooking

1/2 to 1 teaspoon fine sea salt, to taste

Freshly chopped cilantro, about 2 tablespoons, for garnish

Orange slices or thin wedges, for serving (optional but nice)

How to Make this

Print Recipe (No Advertisments)

1. Pat the steak dry with paper towels, sprinkle 1/2 to 1 teaspoon sea salt over it, then toss the slices in 1/3 cup arrowroot starch until well coated and shake off excess.

2. Mix the sauce in a bowl: 1/2 cup fresh orange juice, 1 teaspoon orange zest, 1/4 cup coconut aminos, 1 tablespoon apple cider vinegar, 1 tablespoon freshly grated ginger, and 1 tablespoon garlic infused oil. Set aside.

3. Heat a large skillet or wok over medium high heat until hot, add 2 tablespoons coconut oil. Work in batches so the pan stays hot and the beef can sear.

4. Add a single layer of dredged steak, sear about 1 to 2 minutes per side until browned and slightly crisp at the edges, then transfer to a plate. Repeat with remaining beef, adding a bit more oil if needed.

5. Lower heat to medium, pour the orange sauce into the hot pan and scrape up any browned bits, bring to a gentle simmer.

6. Make an arrowroot slurry by whisking 2 tablespoons arrowroot or tapioca with 2 to 3 tablespoons cold water until smooth. Slowly whisk the slurry into the simmering sauce and cook 1 minute until it thickens. If it is too thin, add a little more slurry, but add in tiny amounts because arrowroot thickens fast.

7. Return all the seared beef to the pan, toss in the sauce for 1 to 2 minutes so the meat is coated and heated through. Taste and adjust with a pinch more salt if needed.

8. Remove from heat, sprinkle about 2 tablespoons freshly chopped cilantro over the top, and serve immediately with orange slices or thin wedges if you want a pretty touch.

9. Leftovers store well in the fridge up to 3 days, reheat gently so the sauce doesnt break and stir in a splash of water if it thickens too much.

Equipment Needed

1. Large heavy skillet or wok
2. Cutting board and a sharp chef knife
3. Mixing bowls (one for sauce, one for dredging)
4. Tongs or a slotted spatula for flipping and tossing
5. Measuring cups and spoons
6. Whisk for the arrowroot slurry and sauce
7. Paper towels and a plate for resting the seared beef

FAQ

Q: Can I use tapioca instead of arrowroot for dredging and thickening? A: Yes, tapioca works fine, but arrowroot gives a silkier, clearer finish. Use the same amount, but if the sauce looks cloudy or gummy, cut the starch by a quarter next time.

Q: I don't have coconut aminos, can I use soy sauce? A: You can, but that removes the gluten and soy free benefit. If gluten is a problem use tamari that is labeled gluten free. Taste first and cut the salt elsewhere because soy is saltier than coconut aminos.

Q: My sauce is too thin, how do I thicken it without lumps? A: Make a slurry by whisking arrowroot with a little cold orange juice, then pour it into the simmering sauce off heat and stir, the heat will thicken it quickly. Arrowroot can seize if boiled too long so add near the end and don't overcook.

Q: How long should I marinate the steak, and does it need to marinate at all? A: You can toss the beef in a little coconut aminos and arrowroot for 10 to 20 minutes to help flavor and texture, but it does not need an overnight marinade. Longer than a few hours won't make a huge difference for thinly sliced flank or skirt steak.

Q: What's the best way to slice the steak so it's tender? A: Freeze the steak for 20 to 30 minutes so it's firmer, then slice very thin against the grain. Cutting against the grain shortens the muscle fibers and keeps every bite tender, otherwise it can be chewy.

Q: How do I store and reheat leftovers without drying the beef out? A: Cool quickly and store in an airtight container for up to 3 days. Reheat gently in a skillet with a splash of water or orange juice over medium low heat, cover briefly to steam, don't blast it on high or the meat will get tough.

Orange Beef (gluten & Soy Free) Recipe Substitutions and Variations

1 pound flank or skirt steak — Substitutes:
- Skirt steak (if you started with flank) or vice versa, both slice thin against the grain
- Top sirloin, trimmed and thinly sliced, slightly leaner but works great
- Flank pork or pork shoulder thinly sliced, cooks a bit faster and stays tender
- Chicken thigh, boneless and skinless, sliced thin for a lighter version
Arrowroot starch for dredging and thickening — Substitutes:
- Tapioca starch, basically the same texture and glossy finish
- Potato starch, good for thickening but don’t boil long or it can thin out
- Instant mashed potato flakes in a pinch, use sparingly and whisk well
- Rice flour, works for dredging though less glossy in the sauce
Coconut aminos — Substitutes:
- Worcestershire sauce, use less cause it’s stronger and not as sweet
- Bragg liquid aminos if soy is okay for you, similar salty umami
- Homemade mix: beef or chicken broth plus a little maple syrup and salt
- Tamari if you can do gluten but need soy free swap, watch salt levels
Coconut oil or avocado oil for cooking — Substitutes:
- Ghee or clarified butter, adds rich flavor and tolerates high heat
- Light olive oil, use for medium heat and a milder taste
- Sunflower oil, neutral and good for high heat searing
- Beef tallow, for a deeper, beefy flavor if you want more richness

Pro Tips

1) Let the meat come closer to room temp for 20 minutes before cooking. It sears faster and more evenly that way, so you wont end up with an overcooked outside and cold center.

2) Dredge and shake off excess arrowroot, then press the coating onto the slices with your fingers. A thin, even layer crisps better and sticks during searing. If you pile it on it can clump and steam instead of getting golden.

3) Work in very small batches and dont overcrowd the pan. Keep the oil hot between batches and wipe out any burnt bits if they build up, or the next batch will taste bitter. If you need, heat the pan back up for 30 seconds before adding more meat.

4) Add the arrowroot slurry slowly, off the boil at first, and only a tiny bit at a time. Arrowroot thickens fast and if you over-thicken the sauce it can become gluey when reheated. If sauce splits later, stir in a splash of cold orange juice or water and rewarm gently.
