Here’s What We Used For These Top Sirloin Steak Caprese Skewers with Walnut Pesto:​

What Is Top Sirloin Steak?

According to this article, top sirloin steak is a cut from the primal loin or subprimal sirloin. This cut of steak differs from a sirloin steak because the bone and the tenderloin and bottom round muscles have been removed. Top sirloin steak is a naturally very lean cut of meat! It has a bold, beefy flavor that we just absolutely love! It’s also a very firm piece of meat that makes it great for cutting up into bite sized pieces to cook on a grill pan. It holds it shape very easily. While we don’t always opt for leaner cuts of meat, this top sirloin steak is perfect for when we are trying to keep our calories down, but get all the benefits of protein and nutrients that steak provides.

Bri especially likes to keep her macros in check, so sometimes a leaner cut of meat is the way to go. We do enjoy sirloin cuts from time to time, like this Sirloin Steak Salad Recipe with Fresh Mozzarella and Roasted Vegetables. According to this article, top sirloin steak is perfect for grilling since it is a more firm piece of meat.

How Do I Make The Walnut Pesto?

We have a very detailed post for our walnut pesto recipe if you are looking for tips and tricks on how to best prepare it! A traditional pesto alla genovese is made with fresh basil, grated parmesan, garlic, olive oil, salt and pepper, and pine nuts. You could certainly use pine nuts in this recipe to make it the traditional way, but to be honest, we didn’t have any, so we used some walnuts. Walnuts are a great substitute. Basically, to make your own pesto, all you have to do is combine all of those ingredients in a food processor and combine.

How Do I Prepare These Skewers?

For this recipe, and really any recipe that involved both grilled meats and vegetables, we like to grill each component individually. You know you’ve seen it. Meat and veggies on one skewer, cooking at the same time? While it looks pretty, it’s really not very great to do in real life. The reason for that is, meat and each individual vegetable cook at different times! For instance, the tomatoes will blister up much faster than the onions due to their high water content. Steak also needs a bit more time then tomatoes.

To make sure that everything is cooked to perfection, we recommend placing each item on separate skewers so you can control the cook better. Basically just put some salt, pepper and oil on each of the ingredients, place them on their skewers, then add them to a smokin hot grill. Cook them until they self release, so you get some nice grill marks on them. Once everything is cooked, you can reassemble separate skewers with all of the ingredients (including your mozzarella cheese and basil) so that all of the ingredients are alternating.

How Long Can You Save The Leftovers?

The walnut pesto in an air tight container like a jar in the fridge, and It will keep for 7-10 days, if it will last that long! For the steak and vegetables will last 3-5 days in an airtight container in the fridge. The tomatoes may become a little more soggy, so keep this in mind. To reheat, you could broil, reheat in a skillet, or even microwave, but the steak
