Paleo Fajita Steak Soup (Instant Pot & Stove Top Option)

Fajita Steak Soup is so flavorful and simple to make! This healthy Mexican-inspired soup combines the flavors of lean beef, peppers, cauliflower rice, onions, and tomatoes. Paleo and whole30 friendly ingredients, light, and quick to make in the instant pot or stove top!

It’s cold. There’s a blizzard. We need soup; spicy fajita steak soup!

The meal prep challenge may be over, but I still find myself thinking in that matter. Meal prep that is. Easy to prep and easy to make recipes! Recipes made with simple nourishing ingredients. Yes, SIMPLE yet Flavorful. I guess that means the anti-inflammatory meal prep challenge has had a lasting effect on me. Do I get bonus points for that? Haha, no, but if you practice something on a consistent basis, it becomes a habit! And I plan on making meal prep a HABIT! AMEN AMEN!

So there I stood Sunday morning… standing in my kitchen planning for Sunday dinner and a few meal prepped lunches for the week. It was cold. It was snowy. And the only thing on my mind was a spicy soothing soup. One that you could batch cook and freeze.

You’re thinking exactly what I’m thinking (or was thinking that day), yes?

Mexican FOOD made in the instant pot (or stove top). But not just any mexican recipe, an extra spicy beefy fajita-ish recipe!

INSTANT POT STEAK SOUP with a MEXICAN FAJITA Twist!

In other words…

A pressure cooker recipe for steak fajitas in a spicy soup form.

WINNING!

But remember, there a STOVE TOP OPTION TOO! So even if you don’t have an instant pot (yet), you can make this soup. It’s a must must must make!

STEAK COOKING TIP:

Quick note —> If you ever want to practice to searing steaks, you can practice by making this Mexican steak soup. How so? Well, in order to make the soup I first seared (browned/sauteed) lean steaks in the instant pot. All you do is add a bit of oil and pepper. Use the saute mode (or medium high on the stop top) to cook 2 steaks, flip a few times, then remove from heat. Let the steaks rest a bit while you prep the other ingredients. Then slice and sprinkle with sea salt. Taste if you’d like!

Then, once you have everything prepped for the soup, simply throw it all back in the instant pot or stock pot to cook, including the steak strips.

So you see, even if you mess up searing steak (which is really just as easy as searing salmon), you will have use for it.

Okay let’s talk about what’s in it and a nerdy nutrition tip. Mmmmk ?

Ingredients to make a paleo Mexican-inspired soup:

• Lean beef (steak sirloin) – Good source of lean protein and heme Iron. 
• Cauliflower rice (always handy) – Cauliflower is also rich in Vitamin K, which  can improve bone health by improving calcium absorption. 
• Bell Peppers – Rich in Vitamin C
• Onion and garlic- Garlic may have the ability to help lower the bad LDL cholesterol while not affecting the good HDL cholesterol. 
• Salsa or pico de gallo
• Diced Tomatoes – Rich in lycopene (antioxidant that supports skin and immune system).
• Jalapeño and Cilantro –
• Chicken Broth – If you add bone broth to the soup, you’ll sneak in extra protein, Plus the collagen and amino acids are great for gut health. 
• Mexican spice  like cumin, chili powder – anti-inflammatory properties
• Avocado to top – Healthy fats! YASSSS! Caveman approved. 🙂 

I realize you may be thinking… this is such a hodge podge Mexican beef and vegetable soup. To which I would then respond….. YES! And one you will your taste buds will forever remember!
