Fall is a fabulous time to cook using seasonal ingredients– but it’s not just the season for apples and pumpkins. This easy steak taco recipe highlights the flavors of Autumn using butternut squash, shallots, and the quality of meat we recommend using, which is grass-fed beef from a purveyor like Arrowhead Beef. (Their beef is pasture-raised, grass-fed, and grass finished. Read more about why this is important in our “Notes” section, below.)
Butternut squash (another quintessential Fall staple) and shallots make an excellent compliment to steak, which is a heartier meat that many people start cooking once the weather starts to cool. We love Arrowhead Beef’s grass-fed steak and think it’s a perfect match for this autumnal steak preparation with squash and shallots. This easy, delicious steak taco recipe features medium-rare sirloin steak, which is the healthiest preparation of steak in terms of iron absorption, digestibility, and flavor. (To learn more about why medium-rare steak is better for you, go here.)
This delicious steak taco recipe is also quick to prepare and beautiful to look at. (Two important considerations when you’re hosting or time is limited!) We loving serving these steak tacos with a few generous lime wedges, which brighten the whole dish and make the recipe seem more sophisticated than it is. (See images, below.👇)
Also: iron deficiency is on the rise among women in the Western hemisphere, and steak is pretty much the best way to get it. (But that’s an article for another time.) We suggest buying grass-fed beef whenever possible for maximum health benefits. Most importantly: once you make these steak tacos, you’ll never go back to any other steak recipe. They are so good!
These delicious steak tacos are so easy, colorful, nutritious, and they present beautifully. They make a great late summer/early Fall meal for when the weather is crisp and you want to eat something fresh and seasonal. The secret here rests in the delicious caramelized shallot reduction that flavors the steak. This carries over into the taco, giving the meat a rich, umami flavor with minimal effort.
Delicious Squash & Steak Tacos Recipe
- 1 medium butternut squash, roasted and diced
- 2 lbs sirloin steak (we used a large grass-fed Tri Tip sirloin from Arrowhead Beef, cut into two big pieces)
- 1 jar salsa or red chile sauce
- 4 avocados, sliced
- 6 shallots (diced), 3 diced shallots reserved
- 2 cups chopped cilantro (those who don’t like cilantro can use parsley)
- 20 small corn tortillas
- paprika to taste
- coriander powder to taste
- salt/pepper to taste
- avocado oil
- 2 tablespoons butter
- Pre-heat oven to 350 degrees. Bake whole butternut squash for 1 hour on cookie sheet or roasting pan. Cool, cube, and sprinkle with salt and pepper.
- Dry steak with a paper towel then rub with avocado oil and sprinkle with salt and pepper.
- Heat a cast iron skillet to medium-high until a drop of water sizzles when it hits the pan.
- Drop 3 diced shallots into the pan with a pour of avocado oil. Cook until slightly caramelized, about 2 minutes at low/medium heat. (Set aside remaining shallots for garnishing tacos. Do NOT let these shallots burn!)
- Leave cooking shallots in the skillet and push them to the side as you drop in your steak. Cook steak on hot skillet for 5 minutes. Flip over, then cook until medium-rare, about 5-6 minutes more. (This is an image of “medium-rare streak” for reference. If you’re using a meat thermometer to test for medium-rare, the center temperature should reach 125 degrees at the thickest part of the steak.) For thicker steaks, add a 2-3 minutes to the cook time on each side. When steak is finished cooking, it should have a nice “crust” but it should still be pink and juicy in the middle.
- Remove steak from pan and let meat rest for 10 minutes. Melt 2 Tablespoons of real butter on top of the steak as it rests, and pour caramelized shallots from the pan over the top of the steak, to let the flavors settle.
- After 10 minutes, thinly slice the steak. Then, place a few pieces of meat in a warm tortilla and layer with toppings– squash, shallots, salsa, avocado, cilantro, a squeeze of lime, paprika, coriander, salt and pepper. Enjoy!
Notes on This Steak Taco Recipe
- These steak tacos make for a super easy and FAST dinner if you cook and cube the butternut squash ahead of time. You can also purchase pre-cubed butternut squash and roast them until fork tender, if you don’t want to deal with cutting it. Then, you’ll just need to spend ~15 minutes cooking and slicing the steak for tacos (just put out all the ingredients and let diners built their own bite). Great for kids and dinner parties!
- Also, don’t let those shallots burn! When you are caramelizing the diced shallots, be sure to use low heat and only cook them half way before you up the heat to medium and add the steak. If they are too done when you add the steak, they might burn before the steak is finished cooking. This will leave the meat with a slightly carbon-y taste, which you obviously don’t want.
- Finally, if you don’t like corn tortillas, use flour ones. This steak taco recipe will no longer be #glutenfree, but we’re flexible like that.
Notes on Iron Deficiency
- Most steak tacos recipes will naturally be high in iron. But, the naturally occurring vitamin C in lime juice, salsa, and cilantro will help your body better absorb the iron in this steak. Conversely, because calcium blocks the absorption of iron, we’ve omitted cheese and sour cream from this recipe– but you won’t miss it. The caramelized shallots in these steak tacos are a delicious flavor bomb!
Why Using Grass Fed Beef Is So Important
Very often, meat vendors can claim that beef is “grass-fed” if the cows ate grass at some point in their lives, and because the guidelines are this ambiguous, not all grass-fed beef is created equal. You really have to trust your farmer. Grass fed beef has a higher concentration of a naturally occurring beneficial fat called conjugated linoleic acid (or CLA), which has been tied to improved immunity. (It’s also a natural anti-inflammatory.)
Grass fed beef is also higher in a host of vitamins, omega-3’s, and trace minerals like iron. These nutrients and healthy fats don’t occur (or occur in significantly lower quantities) in non-grass fed beef, which is usually produced from cows who ate grains (which are NOT a natural part of their diet). Consequently, grain-fed cows require treatment with antibiotics and other chemical medications to keep their digestion going, and these toxins end up in the meat. Also, grass fed beef is better for the environment, because grazing helps restore ecosystem balance. If you’re going to eat red meat, organic and grass-fed is the way to go.
