Heat 1 tsp oil in a LARGE POT or DEEP SKILLET over high heat. Add bacon & cook until fairly crisp. Blot on paper towel & crumble. Transfer to a small microwave-proof bowl. Leave about 1 Tbsp bacon drippings in pot & discard the rest. Add mushrooms & cook until browned. Remove to a dish, set aside.
Add wine & cook, scraping the bottom of the pot to get any brown bits, about 2 minutes. Turn down heat to medium-low; add about 3 cups of chicken stock. Leave, uncovered, stirring just once or twice, until most of the liquid has been absorbed.
Check firmness of rice & add 1/2 cup of broth at a time, stirring in between until absorbed & rice is cooked to YOUR taste.
Add the mushrooms back into the risotto towards the end, just to heat through. Right at the end when the risotto is ready, add a ‘splash’ more chicken broth to make the risotto slightly soupy, then take it off the stove.
Add butter & Asiago cheese, then stir vigorously (this will activate the starch & make it super creamy). Add shrimp & gently stir to incorporate them into the risotto.
Serve immediately. Garnish with reheated bacon & extra Asiago if you wish.
