I couldn’t verify a specific olive oil brand or type Joanna Gaines uses from the information available here. The search results only point to Joanna Gaines recipe content and Magnolia-related articles, but nothing that clearly names her olive oil choice.

What can be said

  • Joanna Gaines is publicly associated with Magnolia Table recipes and cooking content, but the available result snippets do not identify a particular olive oil.
  • One related result mentions extra-virgin olive oil in a separate Martha Stewart article, not Joanna Gaines.

Most likely answer

If you’re asking about her general cooking style, the safest answer is that she appears to use standard extra-virgin olive oil in home cooking contexts, but I can’t confirm a specific brand or bottle from the sources available here.

Note

The search results available do not support a more precise claim, so I’m avoiding guessing.
