How Grass-Fed Beef Cooks
Grass-fed beef has a different fat profile, firmer muscle fibers, and a cleaner flavor than
grain-fed. It cooks faster and benefits from moderate heat and shorter cooking times.
Because there is less intramuscular fat, heat travels through the meat more quickly. This is
why grass-fed beef can go from perfect to overdone faster than you expect.
Practical guidance:
- Expect 20-30% faster cooking times.
- Use medium or medium-low heat for most methods.
- Keep it under medium-well unless absolutely necessary.
- Rest the meat to stabilize juices.
- The best thawing method is slow refrigerator thawing. Steaks take 24-48 hours; roasts
need 2-3 days.
- Cold-water thawing works if you’re short on time: submerge sealed packages in cold water,
replacing water hourly.
- Never thaw on the counter or in hot water - both destroy texture.
Best practice: after thawing, let meat sit in the fridge uncovered for a day to dry the surface
and deepen flavor.
The red liquid in the package isn’t blood; it’s myoglobin. Grass-fed beef tends to show more
of it because the muscle fibers are denser and hold moisture differently.
Dry brining draws moisture to the surface, dissolves the salt, and pulls it back into the meat
for better seasoning.
Instructions:
- Use ¾-1 tsp kosher salt per pound.
- Refrigerate steaks uncovered for 12-24 hours.
- Refrigerate roasts loosely covered.
This deepens flavor, improves browning, and naturally tenderizes.
Note: The small amount of avocado oil raises the smoke point and protects the butter from
burning, allowing the butter to brown the meat properly without scorching.
Proper searing builds flavor and color. Grass-fed beef benefits especially from a well-
developed crust.
Use 1 tbsp avocado oil (high smoke point) followed by 2 tbsp butter for flavor and
browning.
Heat cues:
- Oil should shimmer.
- Butter should foam but not burn.
- A drop of water should dance on the pan.
Pat meat completely dry - moisture is the enemy of browning.
1. Preheat cast iron on medium-high 4-5 minutes.
2. Add 1 tbsp avocado oil.
3. Add 2 tbsp butter once oil is hot.
4. Lay steak away from you.
5. Sear 1.5-2.5 minutes per side.
6. Baste with the butter-oil mix.
7. Finish thicker steaks in a preheated 300°F oven for about 5-10 minutes, depending on
thickness at 300°F if needed.
8. Rest 5-10 minutes.
Browning is your friend - burning is not.
Reverse searing gives you perfect edge-to-edge doneness.
Instructions:
- Cook at 225-250°F until meat is 10-15°F below your target.
- Sear in a hot pan or grill 45-60 seconds per side.
This prevents overcooking and enhances tenderness.
For steaks:
- Smoke at 180-225°F until 115-120°F internal.
- Finish with a hot sear.
For roasts:
- Smoke at 225°F.
- For sliceable roasts, go to 135-145°F.
- For shreddable, go to 195-203°F.
Use oak or hickory pellets for richer smoke.
Sous Vide - Full Method
Grass-fed beef benefits greatly from sous vide because the precise temperature control
protects lean muscle fibers from overcooking. It’s one of the best ways to get perfectly
tender, evenly cooked steaks or roasts - especially with the naturally lean profile of
Highland cattle.
**Steaks vs. Roasts (Key Differences):**
- **Steaks** cook relatively quickly and primarily need precise doneness and a great final
sear.
- **Roasts** benefit from longer sous vide times (3-6 hours or more) to break down
connective tissue slowly without drying out.
**Recommended Temperatures:**
- Medium-rare: **129-131°F**
- Medium: **135-140°F**
- Above medium is not recommended for most grass-fed cuts, as they firm up quickly.
**Timing:**
- Tender steaks (ribeye, strip, sirloin): **1.5-2 hours**
- Lean steaks (round, flat iron): **2-3 hours**
- Roasts (chuck, sirloin tip, rump): **3-6 hours** depending on thickness
**Bagging Tips:**
- Use salt lightly-full seasoning happens after searing.
- Add a pat of butter or a splash of olive oil in the bag for moisture.
- Aromatics like thyme, rosemary, bay leaf, garlic, or peppercorns may be added
**sparingly** so they don’t overpower the clean grass-fed flavor.
**Post-Sous-Vide Critical Step - Drying the Surface:**
The surface must be **thoroughly dried** before searing. Moisture will cause steaming
instead of browning. Use paper towels to pat completely dry.
**Searing After Sous Vide (Critical for Flavor):**
- Use our standard searing method:
• Heat a cast-iron skillet until hot.
• Add **1 tbsp avocado oil** first.
• Add **2 tbsp butter** once oil shimmers.
- Sear **30-45 seconds per side** for steaks.
- For roasts, sear each exposed surface to develop color and caramelization.
**Final Notes:**
- Always rest briefly after searing.
- Avoid letting sous vide steaks sit too long after the bath-they lose heat quickly.
- Sous vide gives you tenderness and precision, while the final hot sear brings the true depth
of flavor.
Slow cooking transforms tough cuts by breaking down collagen.
Guidelines:
- Sear meat first.
- Add 1-2 cups of broth or wine.
- Add onions, garlic, and herbs.
- Cook on low 6–8 hours.
- Oven braise 3-4 hours at 275°F.
If it’s tough, it simply needs more time.
Quick-cook cuts like skirt, flank, sirloin tip, and tenderized round steaks respond extremely
well to fast, high-heat cooking. These cuts are naturally lean and benefit from proper slicing,
brief marination, and very short cook times.
**Slicing Technique:**
- For the most tender results, slice the meat thinly *against the grain*.
- The easiest time to slice is when the meat is **partially frozen** - firm enough to hold
shape but still workable.
- Aim for slices about 1/4 inch thick for stir fry or fajitas.
**Marinating Guidance:**
- These cuts do **not** need an overnight soak - 45 minutes to 2 hours is typically ideal.
- The purpose of the marinade is to add flavor and gently tenderize.
- Good tenderizing ingredients include:
• Citrus juice (lemon or lime)
• A splash of apple cider vinegar
• Worcestershire sauce
• Soy sauce or coconut aminos
• Olive oil
• Garlic, pepper, chili flakes, herbs
- Avoid overly salty marinades for long periods - they can make the meat firm.
**Cooking Method:**
- Preheat a cast-iron skillet or grill to high heat.
- Add a small amount of avocado oil.
- Cook slices **60-90 seconds per side** - no longer.
- Remove immediately and rest briefly.
**Best Uses:**
- Tacos
- Fajitas
- Stir fry bowls
- Asian-inspired dishes
- Quick weeknight meals
Rare: 120-125°F
Medium-rare: 128-132°F
Medium: 135-140°F
Medium-well: 145-150°F

Grass-fed beef shines best medium or below.
Troubleshooting Common Mistakes
Tough meat: usually overcooked.
Dry meat: heat too high.
Steamed instead of seared: meat too wet.
Bitter crust: butter burned.
Shredded roast still tough: cook longer.
