Add your beef bacon slices to a foil-lined pan.
Place the pan in a cold oven, then set the temperature to 390℉. Cook for 8-10 minutes, until crispy.
Remove and place the bacon on paper towels to drain excess grease. Crumble bacon slices into pieces.
In the meantime, fill a large pot with water and a generous amount of salt.
Bring the pot to a rolling boil, then cook your bowtie pasta for 7 minutes.
Reserve ¼ cup of pasta water, then drain the pasta and set aside to cool.
Rinse and slice your grape tomatoes into fourths.
Thinly slice your fresh spinach leaves.
In a large salad bowl, add the pasta, crumbled bacon, sliced tomatoes, and spinach.
Spinach with the salt, black pepper, and oregano.
Mix your homemade ranch with the pasta water, a little at a time, until smooth, to thin it out. You may not use all of the water. Add the ranch dressing to your pasta salad and stir everything until combined.
Serve as is, or let the pasta salad marinate in the fridge for 30 minutes. Enjoy!
