Why Marbling In Beef Is A Good Thing
It’s easy to look at a cut of beef and see all those little flecks of while and think FAT. And, with today’s fat-phobic tendencies, we want to run the other way. (There was definitely a time that we were just this way!)
But, when it comes to beef, not all fat is created equal.
You see, fat = flavor. and those small white flecks of fat you see inside the lean of the meat are called “marbling”.
When choosing a cut of beef, don’t be put off by these bits of fat. Marbling is what contributes to the tenderness, juiciness, and flavor of the meat. This marbling fat is a healthy, monounsaturated fat – the same type of fat that you find in olive oil.
When choosing a roast, you want to look for small flecks of marbling fat that are evenly scattered throughout the cut.
Avoid roasts that look like they have “veins” or channels of fat through them. These channels typically separate different sections of muscle, which can make properly slicing your roast (against the grain) a bit tricky.
Take a look at the many types of Certified Angus Beef® Brand roasts below. You can really see all the nice marbling in the Top Round and Rib Roasts below.
The Perfected Beef Roasting Technique
Now that you know what to look for in your roast. How will you choose which roast to cook?
We’ve talked this App before, and we’ll talk about it again.
Heck, we’ll talk about it to anyone who will listen!
This app is amazing!
Not only does it give you recommended roast cuts for you cooking method with a short description of each roast and recipes, but it also gives you a a roasting timer specifically tested for your cut, weight, and desired done-ness.
The chefs at Certified Angus Beef® Brand roasted many roasts, carefully measuring the temperatures to get their timer to be perfect.
And, thanks to the Certified Angus Beef® Brand chefs, our roasts have always been spot on when we’ve used the App!
Don’t Forget To Sear Your Roast
The roast timer in the Roast Perfect App also includes a nifty trick to seal in the juices of your roast and start creating a perfect, crisp, and flavorful crust.
A common technique when roasting is to pan-sear your meat before placing it in the oven.
But, the Roast Perfect App has you preheat your oven to a temperature that is higher than you will be roasting at. For the first 15 minutes, the roast sears in the oven at this higher temperature. Then, you lower the temperature, and the main roasting happens.
Do you know what really excites us about this trick? No extra pans to clean!
We love how easy this technique has made roasting. It’s simply a matter of seasoning the meat and then popping it into the oven. After that, we can turn our attention to the other elements of the meal, like sides and sauces!

Our Greek Marinated Roast Beef Recipe
For today’s roast we chose a Sirloin Tip Roast.
This value cut is tender, lean, and economical. Quite the win!
We marinated our roast overnight in a Greek-inspired mixture of lemon juice, olive oil, and herbs. The marinade gives the meat a slightly citrus-y flavor that is bursting with savory oregano and garlic.
Tim called it a cross between having a Greek gyro and a Holiday prime rib.
What a party!
Serving Greek Style Roast Beef
To add to the Greek flair, we served the roast with a classic Greek Tzatziki, a creamy yogurt and cucumber sauce.
But, of course, we added a twist.
We love our beef with horseradish, so we decided to throw a little grated, fresh horseradish into the tzatziki to kick it up a notch.
With the fun Greek flavors and the slight horseradish kick from the sauce, this roast is definitely a show stopper that is perfect for the Holiday table!

Greek Marinated Sirloin Tip Roast with Horseradish Tzatziki Sauce
For the Roast
- 3.5 lb Sirloin Tip Roast
- ½ lemon, juiced (roughly 2 Tbsp juice)
- 1 Tbsp olive oil
- 2 garlic cloves, minced
- 1 Tbsp oregano
- 2 tsp salt
- 1 tsp thyme
- 1 tsp paprika
- ½ tsp ground black pepper
For the Horseradish Tzatziki Sauce
- 1 c Tzatziki Sauce
- 1-2 Tbsp fresh horseradish root, peeled and grated*
- ¼ tsp white sugar
For the Roast
- In a small bowl, mix together the lemon juice, olive oil, minced garlic, oregano, salt, thyme, paprika, and ground black pepper.
- Place the roast on a large piece of plastic wrap and coat it with all of the marinade. Wrap the roast tightly with the plastic wrap to seal in the marinade and refrigerate for 6-8 hours.
- Remove the roast from the refrigerator 1 hour before you are ready to roast, to let it come to room temperature.
- Preheat your oven to 450F.
- Place the roast on a rack in a roasting pan (or on a rack in a baking sheet with sides) and place in the oven for 15 minutes.
- After 15 minutes, reduce the heat to 325F and continue roasting for an additional 50 minutes to 1 hour 25 min, until an insta-read thermometer inserted into the center of the roast reads 120-125F. (This will give you a medium rare ending roast.)
- Remove the roast from the oven, tent it loosely with foil, and let it rest for 10 minutes. After resting, the internal temperature should read around 135F.
- Carve and serve immediately.
For the Horseradish Tzatziki Sauce
- While the roast is cooking, make your Horseradish Tzatziki Sauce by mixing the Tzatziki Sauce with fresh grated horseradish root and sugar. This sauce improves with time, so it can even be made immediately after you marinate your roast. Keep it in a sealed container in the refrigerator for up to 1 week.
