SIS - Simple is Smart Tip

This weeks SIS tip – Make a homemade marinade for your flank steak.  I decided a quick recipe for the marinade is the way to go for this week’s feature.  You can purchase a jar of Italian Dressing and use it also.  However, it’s so great to have a quick go-to recipe for a dressing or marinade. 

For this recipe, mix up a double batch and use half of the recipe to marinate the steak. The other half is perfect for dressing a big tossed salad to go with the steak. 

Add together the following:
1/2 cup of each: olive oil, grapeseed oil, and either red or white wine vinegar.
2 Tbsp Italian Seasonings
1 tsp each of the following: minced dried onions and garlic, salt, and crushed red pepper flakes.   

Whisk together all of the ingredients. 

Neuro Nutrition Nugget - Flank Steak

Flank steak is a lean cut of beef that offers several neuro nutrition benefits. First and foremost, it is a rich source of high-quality protein, which is essential for the optimal functioning of the brain and nervous system. Protein helps in the synthesis of neurotransmitters, which are chemical messengers that transmit signals between nerve cells. Additionally, flank steak is packed with essential vitamins and minerals like iron, zinc, and vitamin B12, all of which play a crucial role in maintaining cognitive health. Iron helps in the production of hemoglobin, which transports oxygen to the brain, while zinc and vitamin B12 support the production of myelin, a protective coating around nerve cells. Incorporating flank steak into your diet can help support brain function and promote overall neurological well-being.

Marinate the Flank Steak

Once the marinade is prepared, the rest is easy. Put the flank steak into a ziplock bag and add one cup of the marinade/Italian dressing. Massage the marinade into the steak, then put the steak into the fridge. Once or twice a day, turn the steak over, so each side of the steak is in the marinade. After two or three days, the steak is nicely seasoned, slightly tenderized, and ready to cook.

Grilling the Marinated Flank Steak on the BBQ.  

Before you put the steak on your BBQ, make sure it is hot. A grill pan won’t work as well as the BBQ for grilling a marinated flank steak. 

Here is how:

  1.  Put the steak on the hot BBQ and pour some marinade over the steak.  
  2. Grill the steak until there are char marks on it.  
  3. Flip the steak over and add more marinade.  
  4. Continue to grill, flip, and add marinade until the steak is the desired doneness.  
  5. Discard any leftover marinade.

Slice the cooked steak against or across the grain of the steak.  Farmer Fred slices his steak paper-thin.  He also likes it cooked rare to medium-rare.  If you are fortunate enough to have leftovers, the leftovers make outstanding Philly Cheese Steaks.   

If you have the freezer space, stock up on flank steak when it is on sale.  Marinate it for 2-3 days and then freeze it in the ziplock bag for up to 6 months.  Defrost overnight in the fridge and grill it the next day.

London Broil can be substituted for the flank steak. It isn't as tender but still delicious. Slicing it very thin after it's grilled helps it to taste more tender.
