Can I make the garlic aioli ahead of time?
Yes, prepare the aioli up to 2 days ahead and store in an airtight container in the refrigerator. Stir before using.
What's the best way to cook the bacon for this sandwich?
Bake bacon in a 400°F oven for 12–15 minutes until crispy and evenly cooked, which yields better texture than stovetop frying.
Can I use regular tomatoes instead of heirloom?
Yes, any ripe, firm tomato works, but heirloom varieties have superior flavor and fewer seeds; slice thick to avoid a soggy sandwich.
How do I prevent the sandwich from getting soggy?
Toast the bread thoroughly, spread aioli on both slices, and slice the tomato just before assembly. Layer bacon and avocado to act as barriers.
Can I scale this recipe?
Yes; the aioli and assembly scale easily. Use 1 bacon slice and 1/4 tomato per sandwich, and multiply the aioli base as needed.
